Shaun Dychko headshot

College Physics Answers was created by Shaun Dychko, a teacher with more than 12 years experience teaching high school physics and mathematics, mostly at Point Grey Secondary in Vancouver, Canada. I have taught AP Physics, and all levels of high school mathematics. I studied physics at the University of British Columbia, where I obtained both my B.Sc., and B.Ed.

I sincerely hope these videos will be helpful with your, or your son/daughter's studies. I put a great deal of effort into making them as clear as possible, and finding a balance between being concise while also being thorough enough to raise flags on common mistakes, and making a bit of time for occasional intriguing digressions.

I am also the creator of Giancoli Answers which provides solutions to problems in the textbook Physics: Principles with Applications , 7th and 6th Editions, by Douglas Giancoli.

A set of instructional pages written in an easy-to-understand language and complemented by graphics and Check Your Understanding sections. An ideal starting location for those grasping for understanding or searching for answers.


The Physics Interactives includes a large collection of HTML5 interactive physics simulations. Designed with tablets such as the iPad and with Chromebooks in mind, this user-friendly section is filled with skill-building exercises, physics simulations, and game-like challenges.


Our Video Tutorial provides a video-based alternative to the written Tutorial above. We aim to present relatively short, highly-organized presentations with a strong graphical component on discrete topics. Watch them on our site or follow the links to YouTube. We add videos quite frequently so stop back by if you don't find what you are looking for. Or subscribe to our YouTube channel,  tap the bell , and receive notifications when new videos come out.


A large collection of GIF animations and QuickTime movies designed to demonstrate physics principles in a visual manner. Each animation is accompanied by explanations and links to further information.

Paper Icon


Have you tried a Concept Builder lately? You should. This growing collection of cognitively-rich exercises will focus student attention on discrete learning goals. Filled with interactive elements, this section is the perfect tool for getting students thinking about the meaning of concepts. Perfect for students and 1:1 classrooms using iPads, Chromebooks, and the like. And for Chemistry types, we've added a large collection of Chemistry Concept Builders. 


Minds On Physics - Version 5 is the HTML5 version of Minds On Physics that replaces our App and Legacy versions. Relying on a large bank of carefully crafted questions, Minds On Physics seeks to improve students' conceptions of physics. "MOPs" combines interactive questioning modules with a thorough, question-specific Help system to engage students in an exercise in thinking, reflecting, and learning. Version 5 is our best-yet version of Minds On Physics. There is a fully functional free version and a paid version that integrates seamlessly with our Task Tracker system and offers some rather enticing features.  


Version 2 of the Calculator Pad is now available. Our newest version includes >2500 Physics and Chemistry problems organized into >250 ready-to-use problem sets. Numerical information is randomly-generated. An answer box allows students to solve and check their answers. Most problems are accompanied  by an audio-guided solution that explains how to solve a similar problem while hilighting the habits that can be adopted for solving any problem. Teachers with Task Tracker accounts can modify problems and problem sets and even create their own problems. Task Tracker also allows teachers to assign problems to their students and track their progress. 


Concept Checkers were built to coordinate with the Physics Interactives section of our website. Relying upon our Task Tracker tool to deliver questions, check answers, and track student progress, a Concept Checker is designed to coordinate with an interactive simulation. Use it as a follow-up check to understanding after exploring the simulation. Most sims are accompanied by a Concept Checker. Some sims have Task Tracker code built into the simulation. But not all sims will have a Concept Checker.  Concept Checkers can be used with or without a Task Tracker account. 


The Science Reasoning Center is our most recent upgrade. This section includes about 70 activities that are perfect for encouraging scientific reasoning skills. Students use science and engineering practices, combined with cross cutting science concepts and core ideas from the disciplines of physics (and chemistry) to analyze phenomenon, experiments, and data presentations. We broke ground in April of 2023; we will continue work throughout the 2023-24 school year.


A collection of pages with questions and answers/explanations which serve as reviews or practice. Each review complements a chapter from The Physics Classroom Tutorial.


A variety of question-and-answer pages which target specific concepts and skills. Topics range from the graphical analysis of motion and drawing free body diagrams to a discussion of vectors and vector addition.


Calling all high school juniors: You've trusted The Physics Classroom to help prepare you for that unit exam in physics. Why not trust us to help prepare you for the biggest test of the year - the ACT test? That's right. Let the TPC help you with the ACT.

Pencil Ruler


A collection of classroom ready worksheets for use by teachers with their classes. Pages are synchronized to readings from The Physics Classroom Tutorial and to assignments of The Minds On Physics Internet Modules. And now teachers can purchase The Solutions Guide containing complete answers, explanations and solutions to all worksheets. This is a section of great usefulness to teachers and of little interest to students. The Solutions Guide is available as a Digital Download.


We are building a collection of lesson plans and pacing guides for multiple units for a variety of course types. The lesson plans will provide teachers with a concrete demonstration of how resources at The Physics Classroom can be incorporated into a course. We will also have corresponding pre-built courses available for Task Tracker users that mirror the lesson plans viewed in this section. These pre-built courses allow teachers to easily hit the ground running  with their Task Tracker classes. We expect this project to be completed by August 1, 2024. Until then, we will release content incrementally as we complete it. Teachers can tap the link and view samples of what we currently have completed.


Our Teacher Presentation Pack is a downloadable product that includes nearly 190 Microsoft PowerPoint slide decks, about 170 animations and videos in .mp4 and .gif formats, too-many-to-count stand-alone images, and a Lesson Notes page for every slide deck. The slide decks are compatible with Google Slides. We did our best to make the product ready-to-use and at the same time fully customizable. It's a great tool in the toolbox for any early-career teacher, cross-over teacher, or even veteran teacher.


Writing good tests and quizzes for your physics class just got a whole lot easier! With The Physics Classroom's Question Bank, physics teachers can quickly put together multiple choice and free-response quizzes and tests that target concepts discussed at The Physics Classroom website. The Question Bank is available for purchase as a both a CD resource and as a Digital Download. Use of the Question Bank requires the Microsoft Word application. (Answers are NOT included on the Question Bank.)


Our newest section, the NGSS Corner assists teachers of Physics and Physical Science in aligning their curricula with the Next Generation Science Standards. Numerous resources are identified and their alignment with the NGSS is described.


The Teacher Toolkits provide teachers with packages of online resources (simulations, movies, animations, demonstration ideas, etc.) that are organized around a topic and a set of learning objectives. These resources, when combined with the numerous resources on our own site, allow teachers to plan high-quality, engaging instruction and to map out a curriculum that is NGSS-based.


While you explore the approximately 150 labs here at The Laboratory, you will likely generate some questions about how they are used and how you can use them. This page, and the pages it links to, are hoped to provide some answers to those questions.


The Photo Gallery provides teachers a toolbox of physics-relevant photos from the wealth of photos on Flickr. The Photo Gallery offers teachers three things: access to photos, organized by topic; a collection of nearly 30 galleries; and an invitation to join this exciting project of capturing and sharing physics phenomenon with a camera. Of course, students are welcome to participate as well.

  • Video lessons to explain complicated concepts was one of the best aids when I wanted to get my licensure and the ability to grow in another area. provided everything I needed and answered all my questions for continued education. helped me with two major tests. It was easy to use and it got me a social work license as well as my teaching certification. I am a huge advocate for the program. The pacing is great and the text and videos are helpful.

I am in education, and needed to take an exam to add another credential to my certification. had the best study guide available for the money and it is broken up into easy to learn modules. This certification is a doozy and the bite sized lessons are not so overwhelming, easy to process and retain. is awesome!! They simplified the math concepts for me and I passed it on my first attempt. The videos are precise and clear. You cannot go wrong with I recommend it.

This was the most helpful studying service I have ever received. I have tried multiple services, lots of studying on my own, and flash cards. I have failed many times and couldn't do better. This was the one that helped me the most and at the end I finally passed.

The app is simple and the practice tests helped me know specifically what I needed to study. Passed my test with flying colors thanks to!

Perfect for what I needed it for! The quizzes and lessons were thorough and I got in a few practice tests before my real one.

The lessons were relevant and easy to understand. I loved that I could watch videos and use audio mode to listen while driving or doing other things.

This website was a great resource for me when I was studying for my certification tests. helped me to pass my tests, and I don't know if I could have achieved that without this resource!

Excellent content. It was directly related to my test. really did a good job at getting to the meat and potatoes of the content.

This service is fantastic! Not only did I passed all the exams I was studying for, I learned something from my studies rather than just memorizing boring facts to be lost in a brain dump later. The content, context, and multiple modes of representation they provide is highly effective and enjoyable!

If it wasn't for I would not have known exactly what it was that I needed to study. It most DEFINITELY was the reason I passed my three super challenging tests!

  • My week-long kinematics approach, including the facts



Greg- I am inspired to drastically shrink my own AP class' kinematics curriculum . Gaming out how that would impact my current other units, do you consider this coverage to also include projectile motion? Or do you discuss this later? Or not at all since projectiles seem to have a negligible effect on the AP exam? Thanks!

Ryan, I do cover projectiles, in an additional one or two classes. For my upperclassmen, I begin the year with a week or so of equilibrium problems - thus, they know how to break a force into components. So projectiles become a review of this process, since they need to break velocity into components. And once they can break velocity into components, projectile kinematics becomes just an extension of one-dimensional kinematics. (For my 9th grade, I start the year with kinematics, and THEN I move into equilibrium and N2L. So, I come back to projectiles after we finish discussing N2L problem solving. The same pedagogical principle applies, though, that we're reviewing the idea of breaking a vector into components, but in context.

Hi Greg, I absolutely love your blog - as a 10 year veteran aspiring AP Physics teacher.. heh heh.. I am always looking for new hacks, tweaks, and general ways to get better. I have been trying to move toward inquiry and have had a bit of success in lab, and I love the philosophy of engaging the students in hands on work and demos as much as possible. I am feeling a sense of eager exhilaration and freedom at the possibility of reducing my formal treatment of kinematics to a mere two weeks, but I'm wondering about handing my students a sheet of facts - as you alluded to above, it feels a bit like it flies in the face of wanting them to build a deeper understanding. Can you maybe say a little more about how you revisit this later to build the enduring understanding? It is something you do deliberately, or does it just come from the study of later topics organically? I'm trying to see the flow as it comes up later - maybe unbalanced forces - for example, would you then look at the motion and have them sketch graphs commensurate with a given scenario? Or something like that?

Lisa, it’s organic... I guess the best way to think about it is that kinematics becomes fair game as part of any physics problem that comes up. The N2L practice requires a reinforcement of the definition of acceleration, and then of kinematics. So many problems use kinematics to find acceleration, and then N2L to find the value of a force; or vice-versa. That right there is a “review”. Projectile motion is next, which is just kinematics but twice. Circular motion allows us to consider the conditions under which we can use “speed = distance / time”. Momentum problems often have a kinematics component, say after or before a collision. Our labquests produce velocity- and position-time graphs, which must be read in order to get useful data out; and we use these for momentum, energy, all kinds of labs. Lots of opportunities. Each time, the students have to use their fact sheet and their (originally hesitant) skill in kinematics problem solving to do kinematics *in context*, not just as something Mr. Jacobs told them to do for homework. An so the concepts stick. By year’s end, kinematics is second nature.

Sat / act prep online guides and tips, how to do homework: 15 expert tips and tricks.

author image



Everyone struggles with homework sometimes, but if getting your homework done has become a chronic issue for you, then you may need a little extra help. That’s why we’ve written this article all about how to do homework. Once you’re finished reading it, you’ll know how to do homework (and have tons of new ways to motivate yourself to do homework)!

We’ve broken this article down into a few major sections. You’ll find:

  • A diagnostic test to help you figure out why you’re struggling with homework
  • A discussion of the four major homework problems students face, along with expert tips for addressing them
  • A bonus section with tips for how to do homework fast

By the end of this article, you’ll be prepared to tackle whatever homework assignments your teachers throw at you .

So let’s get started!


How to Do Homework: Figure Out Your Struggles 

Sometimes it feels like everything is standing between you and getting your homework done. But the truth is, most people only have one or two major roadblocks that are keeping them from getting their homework done well and on time. 

The best way to figure out how to get motivated to do homework starts with pinpointing the issues that are affecting your ability to get your assignments done. That’s why we’ve developed a short quiz to help you identify the areas where you’re struggling. 

Take the quiz below and record your answers on your phone or on a scrap piece of paper. Keep in mind there are no wrong answers! 

1. You’ve just been assigned an essay in your English class that’s due at the end of the week. What’s the first thing you do?

A. Keep it in mind, even though you won’t start it until the day before it’s due  B. Open up your planner. You’ve got to figure out when you’ll write your paper since you have band practice, a speech tournament, and your little sister’s dance recital this week, too.  C. Groan out loud. Another essay? You could barely get yourself to write the last one!  D. Start thinking about your essay topic, which makes you think about your art project that’s due the same day, which reminds you that your favorite artist might have just posted to you better check your feed right now. 

2. Your mom asked you to pick up your room before she gets home from work. You’ve just gotten home from school. You decide you’ll tackle your chores: 

A. Five minutes before your mom walks through the front door. As long as it gets done, who cares when you start?  B. As soon as you get home from your shift at the local grocery store.  C. After you give yourself a 15-minute pep talk about how you need to get to work.  D. You won’t get it done. Between texts from your friends, trying to watch your favorite Netflix show, and playing with your dog, you just lost track of time! 

3. You’ve signed up to wash dogs at the Humane Society to help earn money for your senior class trip. You: 

A. Show up ten minutes late. You put off leaving your house until the last minute, then got stuck in unexpected traffic on the way to the shelter.  B. Have to call and cancel at the last minute. You forgot you’d already agreed to babysit your cousin and bake cupcakes for tomorrow’s bake sale.  C. Actually arrive fifteen minutes early with extra brushes and bandanas you picked up at the store. You’re passionate about animals, so you’re excited to help out! D. Show up on time, but only get three dogs washed. You couldn’t help it: you just kept getting distracted by how cute they were!

4. You have an hour of downtime, so you decide you’re going to watch an episode of The Great British Baking Show. You: 

A. Scroll through your social media feeds for twenty minutes before hitting play, which means you’re not able to finish the whole episode. Ugh! You really wanted to see who was sent home!  B. Watch fifteen minutes until you remember you’re supposed to pick up your sister from band practice before heading to your part-time job. No GBBO for you!  C. You finish one episode, then decide to watch another even though you’ve got SAT studying to do. It’s just more fun to watch people make scones.  D. Start the episode, but only catch bits and pieces of it because you’re reading Twitter, cleaning out your backpack, and eating a snack at the same time.

5. Your teacher asks you to stay after class because you’ve missed turning in two homework assignments in a row. When she asks you what’s wrong, you say: 

A. You planned to do your assignments during lunch, but you ran out of time. You decided it would be better to turn in nothing at all than submit unfinished work.  B. You really wanted to get the assignments done, but between your extracurriculars, family commitments, and your part-time job, your homework fell through the cracks.  C. You have a hard time psyching yourself to tackle the assignments. You just can’t seem to find the motivation to work on them once you get home.  D. You tried to do them, but you had a hard time focusing. By the time you realized you hadn’t gotten anything done, it was already time to turn them in. 

Like we said earlier, there are no right or wrong answers to this quiz (though your results will be better if you answered as honestly as possible). Here’s how your answers break down: 

  • If your answers were mostly As, then your biggest struggle with doing homework is procrastination. 
  • If your answers were mostly Bs, then your biggest struggle with doing homework is time management. 
  • If your answers were mostly Cs, then your biggest struggle with doing homework is motivation. 
  • If your answers were mostly Ds, then your biggest struggle with doing homework is getting distracted. 

Now that you’ve identified why you’re having a hard time getting your homework done, we can help you figure out how to fix it! Scroll down to find your core problem area to learn more about how you can start to address it. 

And one more thing: you’re really struggling with homework, it’s a good idea to read through every section below. You may find some additional tips that will help make homework less intimidating. 


How to Do Homework When You’re a Procrastinator  

Merriam Webster defines “procrastinate” as “to put off intentionally and habitually.” In other words, procrastination is when you choose to do something at the last minute on a regular basis. If you’ve ever found yourself pulling an all-nighter, trying to finish an assignment between periods, or sprinting to turn in a paper minutes before a deadline, you’ve experienced the effects of procrastination. 

If you’re a chronic procrastinator, you’re in good company. In fact, one study found that 70% to 95% of undergraduate students procrastinate when it comes to doing their homework. Unfortunately, procrastination can negatively impact your grades. Researchers have found that procrastination can lower your grade on an assignment by as much as five points ...which might not sound serious until you realize that can mean the difference between a B- and a C+. 

Procrastination can also negatively affect your health by increasing your stress levels , which can lead to other health conditions like insomnia, a weakened immune system, and even heart conditions. Getting a handle on procrastination can not only improve your grades, it can make you feel better, too! 

The big thing to understand about procrastination is that it’s not the result of laziness. Laziness is defined as being “disinclined to activity or exertion.” In other words, being lazy is all about doing nothing. But a s this Psychology Today article explains , procrastinators don’t put things off because they don’t want to work. Instead, procrastinators tend to postpone tasks they don’t want to do in favor of tasks that they perceive as either more important or more fun. Put another way, procrastinators want to do long as it’s not their homework! 

3 Tips f or Conquering Procrastination 

Because putting off doing homework is a common problem, there are lots of good tactics for addressing procrastination. Keep reading for our three expert tips that will get your homework habits back on track in no time. 

#1: Create a Reward System

Like we mentioned earlier, procrastination happens when you prioritize other activities over getting your homework done. Many times, this happens because homework...well, just isn’t enjoyable. But you can add some fun back into the process by rewarding yourself for getting your work done. 

Here’s what we mean: let’s say you decide that every time you get your homework done before the day it’s due, you’ll give yourself a point. For every five points you earn, you’ll treat yourself to your favorite dessert: a chocolate cupcake! Now you have an extra (delicious!) incentive to motivate you to leave procrastination in the dust. 

If you’re not into cupcakes, don’t worry. Your reward can be anything that motivates you . Maybe it’s hanging out with your best friend or an extra ten minutes of video game time. As long as you’re choosing something that makes homework worth doing, you’ll be successful. 

#2: Have a Homework Accountability Partner 

If you’re having trouble getting yourself to start your homework ahead of time, it may be a good idea to call in reinforcements . Find a friend or classmate you can trust and explain to them that you’re trying to change your homework habits. Ask them if they’d be willing to text you to make sure you’re doing your homework and check in with you once a week to see if you’re meeting your anti-procrastination goals. 

Sharing your goals can make them feel more real, and an accountability partner can help hold you responsible for your decisions. For example, let’s say you’re tempted to put off your science lab write-up until the morning before it’s due. But you know that your accountability partner is going to text you about it tomorrow...and you don’t want to fess up that you haven’t started your assignment. A homework accountability partner can give you the extra support and incentive you need to keep your homework habits on track. 

#3: Create Your Own Due Dates 

If you’re a life-long procrastinator, you might find that changing the habit is harder than you expected. In that case, you might try using procrastination to your advantage! If you just can’t seem to stop doing your work at the last minute, try setting your own due dates for assignments that range from a day to a week before the assignment is actually due. 

Here’s what we mean. Let’s say you have a math worksheet that’s been assigned on Tuesday and is due on Friday. In your planner, you can write down the due date as Thursday instead. You may still put off your homework assignment until the last minute...but in this case, the “last minute” is a day before the assignment’s real due date . This little hack can trick your procrastination-addicted brain into planning ahead! 


If you feel like Kevin Hart in this meme, then our tips for doing homework when you're busy are for you. 

How to Do Homework When You’re too Busy

If you’re aiming to go to a top-tier college , you’re going to have a full plate. Because college admissions is getting more competitive, it’s important that you’re maintaining your grades , studying hard for your standardized tests , and participating in extracurriculars so your application stands out. A packed schedule can get even more hectic once you add family obligations or a part-time job to the mix. 

If you feel like you’re being pulled in a million directions at once, you’re not alone. Recent research has found that stress—and more severe stress-related conditions like anxiety and depression— are a major problem for high school students . In fact, one study from the American Psychological Association found that during the school year, students’ stress levels are higher than those of the adults around them. 

For students, homework is a major contributor to their overall stress levels . Many high schoolers have multiple hours of homework every night , and figuring out how to fit it into an already-packed schedule can seem impossible. 

3 Tips for Fitting Homework Into Your Busy Schedule

While it might feel like you have literally no time left in your schedule, there are still ways to make sure you’re able to get your homework done and meet your other commitments. Here are our expert homework tips for even the busiest of students. 

#1: Make a Prioritized To-Do List 

You probably already have a to-do list to keep yourself on track. The next step is to prioritize the items on your to-do list so you can see what items need your attention right away. 

Here’s how it works: at the beginning of each day, sit down and make a list of all the items you need to get done before you go to bed. This includes your homework, but it should also take into account any practices, chores, events, or job shifts you may have. Once you get everything listed out, it’s time to prioritize them using the labels A, B, and C. Here’s what those labels mean:

  • A Tasks : tasks that have to get done—like showing up at work or turning in an assignment—get an A. 
  • B Tasks : these are tasks that you would like to get done by the end of the day but aren’t as time sensitive. For example, studying for a test you have next week could be a B-level task. It’s still important, but it doesn’t have to be done right away.
  • C Tasks: these are tasks that aren’t very important and/or have no real consequences if you don’t get them done immediately. For instance, if you’re hoping to clean out your closet but it’s not an assigned chore from your parents, you could label that to-do item with a C.

Prioritizing your to-do list helps you visualize which items need your immediate attention, and which items you can leave for later. A prioritized to-do list ensures that you’re spending your time efficiently and effectively, which helps you make room in your schedule for homework. So even though you might really want to start making decorations for Homecoming (a B task), you’ll know that finishing your reading log (an A task) is more important. 

#2: Use a Planner With Time Labels

Your planner is probably packed with notes, events, and assignments already. (And if you’re not using a planner, it’s time to start!) But planners can do more for you than just remind you when an assignment is due. If you’re using a planner with time labels, it can help you visualize how you need to spend your day.

A planner with time labels breaks your day down into chunks, and you assign tasks to each chunk of time. For example, you can make a note of your class schedule with assignments, block out time to study, and make sure you know when you need to be at practice. Once you know which tasks take priority, you can add them to any empty spaces in your day. 

Planning out how you spend your time not only helps you use it wisely, it can help you feel less overwhelmed, too . We’re big fans of planners that include a task list ( like this one ) or have room for notes ( like this one ). 

#3: Set Reminders on Your Phone 

If you need a little extra nudge to make sure you’re getting your homework done on time, it’s a good idea to set some reminders on your phone. You don’t need a fancy app, either. You can use your alarm app to have it go off at specific times throughout the day to remind you to do your homework. This works especially well if you have a set homework time scheduled. So if you’ve decided you’re doing homework at 6:00 pm, you can set an alarm to remind you to bust out your books and get to work. 

If you use your phone as your planner, you may have the option to add alerts, emails, or notifications to scheduled events . Many calendar apps, including the one that comes with your phone, have built-in reminders that you can customize to meet your needs. So if you block off time to do your homework from 4:30 to 6:00 pm, you can set a reminder that will pop up on your phone when it’s time to get started.

How to Do Homework When You’re Unmotivated 

At first glance, it may seem like procrastination and being unmotivated are the same thing. After all, both of these issues usually result in you putting off your homework until the very last minute. 

But there’s one key difference: many procrastinators are working, they’re just prioritizing work differently. They know they’re going to start their homework...they’re just going to do it later. 

Conversely, people who are unmotivated to do homework just can’t find the willpower to tackle their assignments. Procrastinators know they’ll at least attempt the homework at the last minute, whereas people who are unmotivated struggle with convincing themselves to do it at a ll. For procrastinators, the stress comes from the inevitable time crunch. For unmotivated people, the stress comes from trying to convince themselves to do something they don’t want to do in the first place. 

Here are some common reasons students are unmotivated in doing homework : 

  • Assignments are too easy, too hard, or seemingly pointless 
  • Students aren’t interested in (or passionate about) the subject matter
  • Students are intimidated by the work and/or feels like they don’t understand the assignment 
  • Homework isn’t fun, and students would rather spend their time on things that they enjoy 

To sum it up: people who lack motivation to do their homework are more likely to not do it at all, or to spend more time worrying about doing their homework than...well, actually doing it.

3 Tips for How to Get Motivated to Do Homework

The key to getting homework done when you’re unmotivated is to figure out what does motivate you, then apply those things to homework. It sounds tricky...but it’s pretty simple once you get the hang of it! Here are our three expert tips for motivating yourself to do your homework. 

#1: Use Incremental Incentives

When you’re not motivated, it’s important to give yourself small rewards to stay focused on finishing the task at hand. The trick is to keep the incentives small and to reward yourself often. For example, maybe you’re reading a good book in your free time. For every ten minutes you spend on your homework, you get to read five pages of your book. Like we mentioned earlier, make sure you’re choosing a reward that works for you! 

So why does this technique work? Using small rewards more often allows you to experience small wins for getting your work done. Every time you make it to one of your tiny reward points, you get to celebrate your success, which gives your brain a boost of dopamine . Dopamine helps you stay motivated and also creates a feeling of satisfaction when you complete your homework !  

#2: Form a Homework Group 

If you’re having trouble motivating yourself, it’s okay to turn to others for support. Creating a homework group can help with this. Bring together a group of your friends or classmates, and pick one time a week where you meet and work on homework together. You don’t have to be in the same class, or even taking the same subjects— the goal is to encourage one another to start (and finish!) your assignments. 

Another added benefit of a homework group is that you can help one another if you’re struggling to understand the material covered in your classes. This is especially helpful if your lack of motivation comes from being intimidated by your assignments. Asking your friends for help may feel less scary than talking to your teacher...and once you get a handle on the material, your homework may become less frightening, too. 

#3: Change Up Your Environment 

If you find that you’re totally unmotivated, it may help if you find a new place to do your homework. For example, if you’ve been struggling to get your homework done at home, try spending an extra hour in the library after school instead. The change of scenery can limit your distractions and give you the energy you need to get your work done. 

If you’re stuck doing homework at home, you can still use this tip. For instance, maybe you’ve always done your homework sitting on your bed. Try relocating somewhere else, like your kitchen table, for a few weeks. You may find that setting up a new “homework spot” in your house gives you a motivational lift and helps you get your work done. 


Social media can be a huge problem when it comes to doing homework. We have advice for helping you unplug and regain focus.

How to Do Homework When You’re Easily Distracted

We live in an always-on world, and there are tons of things clamoring for our attention. From friends and family to pop culture and social media, it seems like there’s always something (or someone!) distracting us from the things we need to do.

The 24/7 world we live in has affected our ability to focus on tasks for prolonged periods of time. Research has shown that over the past decade, an average person’s attention span has gone from 12 seconds to eight seconds . And when we do lose focus, i t takes people a long time to get back on task . One study found that it can take as long as 23 minutes to get back to work once we’ve been distracte d. No wonder it can take hours to get your homework done! 

3 Tips to Improve Your Focus

If you have a hard time focusing when you’re doing your homework, it’s a good idea to try and eliminate as many distractions as possible. Here are three expert tips for blocking out the noise so you can focus on getting your homework done. 

#1: Create a Distraction-Free Environment

Pick a place where you’ll do your homework every day, and make it as distraction-free as possible. Try to find a location where there won’t be tons of noise, and limit your access to screens while you’re doing your homework. Put together a focus-oriented playlist (or choose one on your favorite streaming service), and put your headphones on while you work. 

You may find that other people, like your friends and family, are your biggest distraction. If that’s the case, try setting up some homework boundaries. Let them know when you’ll be working on homework every day, and ask them if they’ll help you keep a quiet environment. They’ll be happy to lend a hand! 

#2: Limit Your Access to Technology 

We know, we know...this tip isn’t fun, but it does work. For homework that doesn’t require a computer, like handouts or worksheets, it’s best to put all your technology away . Turn off your television, put your phone and laptop in your backpack, and silence notifications on any wearable tech you may be sporting. If you listen to music while you work, that’s fine...but make sure you have a playlist set up so you’re not shuffling through songs once you get started on your homework. 

If your homework requires your laptop or tablet, it can be harder to limit your access to distractions. But it’s not impossible! T here are apps you can download that will block certain websites while you’re working so that you’re not tempted to scroll through Twitter or check your Facebook feed. Silence notifications and text messages on your computer, and don’t open your email account unless you absolutely have to. And if you don’t need access to the internet to complete your assignments, turn off your WiFi. Cutting out the online chatter is a great way to make sure you’re getting your homework done. 

#3: Set a Timer (the Pomodoro Technique)

Have you ever heard of the Pomodoro technique ? It’s a productivity hack that uses a timer to help you focus!

Here’s how it works: first, set a timer for 25 minutes. This is going to be your work time. During this 25 minutes, all you can do is work on whatever homework assignment you have in front of you. No email, no text messaging, no phone calls—just homework. When that timer goes off, you get to take a 5 minute break. Every time you go through one of these cycles, it’s called a “pomodoro.” For every four pomodoros you complete, you can take a longer break of 15 to 30 minutes.

The pomodoro technique works through a combination of boundary setting and rewards. First, it gives you a finite amount of time to focus, so you know that you only have to work really hard for 25 minutes. Once you’ve done that, you’re rewarded with a short break where you can do whatever you want. Additionally, tracking how many pomodoros you complete can help you see how long you’re really working on your homework. (Once you start using our focus tips, you may find it doesn’t take as long as you thought!)


Two Bonus Tips for How to Do Homework Fast

Even if you’re doing everything right, there will be times when you just need to get your homework done as fast as possible. (Why do teachers always have projects due in the same week? The world may never know.)

The problem with speeding through homework is that it’s easy to make mistakes. While turning in an assignment is always better than not submitting anything at all, you want to make sure that you’re not compromising quality for speed. Simply put, the goal is to get your homework done quickly and still make a good grade on the assignment! 

Here are our two bonus tips for getting a decent grade on your homework assignments , even when you’re in a time crunch. 

#1: Do the Easy Parts First 

This is especially true if you’re working on a handout with multiple questions. Before you start working on the assignment, read through all the questions and problems. As you do, make a mark beside the questions you think are “easy” to answer . 

Once you’ve finished going through the whole assignment, you can answer these questions first. Getting the easy questions out of the way as quickly as possible lets you spend more time on the trickier portions of your homework, which will maximize your assignment grade. 

(Quick note: this is also a good strategy to use on timed assignments and tests, like the SAT and the ACT !) 

#2: Pay Attention in Class 

Homework gets a lot easier when you’re actively learning the material. Teachers aren’t giving you homework because they’re mean or trying to ruin your weekend... it’s because they want you to really understand the course material. Homework is designed to reinforce what you’re already learning in class so you’ll be ready to tackle harder concepts later.

When you pay attention in class, ask questions, and take good notes, you’re absorbing the information you’ll need to succeed on your homework assignments. (You’re stuck in class anyway, so you might as well make the most of it!) Not only will paying attention in class make your homework less confusing, it will also help it go much faster, too.

How to Finish Your Homework

Last Updated: May 6, 2024 Fact Checked

In 2018, she founded Mindful & Well, a natural healing and wellness coaching service. She has worked as a Social Studies Teacher, Curriculum Coordinator, and an SAT Prep Teacher.

While studying can differ for different age groups, many of the things that get in the way are the same. Whether it's your environment or time management skills, it easy for things to discourage you from finishing your homework. With a little organization and help, your homework can become approachable.

Managing Your Time

Step 1 Set aside a specific time to do your homework.

  • For instance, try setting aside a time you know you can work well such as an hour or 2 before dinner, or if you're a night owl, after dinner.

Step 2 Take a break every hour.

  • Work in hour blocks, with 50 minutes spent studying and 10 minutes spent taking a break.
  • It can also be helpful to move around when you are taking your break, especially if you are working at a screen. Go for a walk outside to get your blood circulating and enjoy some fresh air.
  • You might also want to eat a healthy snack on your break to improve your focus. Avoid junk food and choose something like a handful of nuts, a piece of fruit, veggies, or a small portion of cottage cheese.

Step 3 Prioritize tasks.

  • Identify which assignments are worth the most points for each class. Most likely these will take the longest to complete. [5] X Research source
  • Consider how long you have to do each project, and if possible, see when the assignment is introduced. Oftentimes, primary and secondary school classes do not have syllabi, so it might be harder to plan out an entire term, but if you are in college, you will most likely have a syllabus with at least a partial course schedule. Knowing how long you have to complete an assignment will help you prioritize which assignments to do first. You can also ask the teacher how long you have to complete an assignment. [6] X Research source

Step 4 Create a study schedule.

  • Use highlighters or stickers to mark which assignments are most important.
  • If you're using an online or mobile schedule, create alerts or notifications for the projects and any time-sensitive steps for those projects.

Step 5 Make sure to complete the most pressing assignments first.

  • Don't let a big project overshadow the smaller assignments you need to complete!

Step 6 Break down larger projects into manageable tasks.

  • Assignment outlines can help you visualize the necessary tasks to get the assignment done.

Step 7 Don't multitask.

Creating a Productive Work Environment

Step 1 Find a comfortable, but not too comfortable, place to work.

  • A desk or table would be a better location than a couch or a bed.

Step 2 Minimize social distractions.

  • Turn your phone off or on silent (not vibrate). It might be best to put the phone out of sight, or in another room while you work, as the temptation to text or get on social media can be as much of a distraction as actually using social media.
  • Use an app that blocks social media. There are plenty of applications out there that can help block social media and other distracting sites (such as shopping or gaming sites). [10] X Trustworthy Source Pew Research Center Nonpartisan thinktank conducting research and providing information on public opinion, demographic trends, and social trends Go to source

Step 3 Minimize noise.

  • Use a white noise app to block out noise.
  • Use earplugs or noise-blocking earmuffs. [12] X Research source
  • Work in a quiet place, such as a library or a home office, if you have one.
  • Avoid listening to music while studying. Studies have shown that although listening to music while studying lowers overall performance, this does not affect everyone equally. [13] X Research source However listening to music before studying has been shown to improve performance on cognitive tasks. [14] X Research source

Step 4 Write down why you need to finish your homework.

Using Your Resources

Step 1 Ask your parents or peers for help.

  • If you're too afraid to ask a teacher during class, see if you can stay behind to ask your questions.

Step 3 Find a tutor (if available).

  • First, contact your school to see if there are any after-school tutoring programs. While not all primary and secondary schools offer tutoring, a vast majority of universities do. If your school does not offer tutoring, they may know of other resources for you to contact.
  • Then, contact your library to see if they offer any tutoring. [18] X Research source
  • In some areas, there may also be free community tutoring programs. Contact your local community center for more information.
  • There are plenty of private tutors out there as well, but they can be costly (ranging from $20 to $100 an hour). [19] X Research source You can find tutors online through a number of websites, such as Craigslist or Angie's list.

Step 4 Go to the library.

  • If you need to work at a library after school, ask your parents or search the web to find your local library.

A metal roller of mass m =1.8 kg moves in a rolling motion on an inclined plane in a uniformly accelerated rectilinear motion. As it moves down the track with s=0.95 m, the body accelerates from the initial velocity v1=1.9 ms-1 to speed v2=2.9 ms -1 . The slope of the inclined plane is β and neglect the friction factor between the body and the pad. Gravitational acceleration of the Earth consider g =9.81 ms-2 . Do not include null members in expressions.

Homework help

Necessity of online homework help.

Contemporary world is a scene for competitions. Starting at early childhood environment immerse us into struggle for best positions. With constant population growth it becomes harder to get a place in kindergartens, schools for gifted children, prestigious universities and, of course, you are not alone in desire to have a well-paid job. Children since early age know that they must study hard, devote themselves into different subjects, and be successful and active in post-school projects. Under pressure of numerous complex tasks no wonder they often require homework help. For their needs special websites were launched. And now every child can get guidance and online homework help from every corner of the world. With opportunity to ask questions about necessary subjects he will at his own pace learn information. This also adds more individuality to process of studying, as children might experience problems with concentrated and fast group-learning. Online homework help is not merely a way to make grades better and to finish all tasks in time, it's personal attention and support. Websites offer plenty of subjects to work at, but according to searches most popular (as it's complicated to understand) is math homework help. This subject is a nightmare for both schoolchildren and their parents.

Why using college homework help is beneficial

It might come as surprise for graduates but when you enter college or university, amount of homework will be only increasing. Yes, besides lectures and practical courses you are obliged to do some homework too. And it might be incredibly more complicated than all things you have done in school. Plenty of students are struggling to cope with amount of tasks themselves but some are looking for websites for college homework help. With current subjects, with unknown teachers, with new classrooms it's stressful enough for young people to be focused. That's why students choose homework help discord, a place to discuss all difficulties online and solve problems. With guidance and support of experts it's easier to understand unknown topics and work on self-improvement. It's recommended not to torture yourself and get accounting homework help or any other kind of assistance. With wide range of professionals you can find a person no matter how complicated your task is.

Is it safe to trust strangers with important tasks?

Looking for online help with college or school tasks you might doubt reliability of person who is assisting you from other side of screen. How is it possible to find a proper tutor for difficult statistics homework help?
