Using the Kinematic Equations to Solve Problems - Part 1

[@mercytorres5906]

my physics teacher could never....thank you sir helped out a lot

[@a.dgirlstar4721]

same mine doesn't know how to teach

[@cja12345]

@@a.dgirlstar4721 same thing here. Bro was using the wrong kinematic formulas… none of them even matched the ones this awesome teacher had smh.

[@Bintu.babyyyy]

Same with me😩

[@JasmineCosta-i7y]

My head was SPINNING and I was in full panic trying to grasp physics, this video was BEYOND helpful. Thank you so so so much!

[@cja12345]

you saved me man. I've been confused with kinematics for the past week and your video is so clear. MAN THANK YOU SOO MUCH

[@PhysicsclassroomVideos]

Glad to hear. Kinematics can be difficult. Get through it and you have a great start.

[@NimaAdineh]

I've been struggling with kinematics for weeks because of the equations, THANK YOU SO MUCH for explaining them! 🙏

[@PhysicsclassroomVideos]

Glad to help!

[@josephineobazuaye555]

Best physics video I've found so far on KZbin. Thank You!

[@PhysicsclassroomVideos]

Wow! Thanks heaps. There's lots of great Physics videos out there. But yes ... we think we're starting to get the hang of this as well.

[@anjali3232]

My children understood kinematics because of ur interesting lectures. Kindly keep doing videos on other topics with a constant positive acceleration :))

[@annahock7307]

Wow i usually never comment on videos and I never understand explanation videos, but this video changed my whole life and understanding of how to use kinematic equations. Thank you so so much.

[@NjaliweMakalani]

The best physics video I've watched lately ❤

[@69Paulita]

Hello, I am so very stumped by physics as of late. I am falling behind. You are helping me to feel more confident. I have to pass this and the other physics classes in order to achieve my bachelor's degree. I need all the help I can get. I appreciate you.

[@PhysicsclassroomVideos]

You can do this! Glad the videos are helping.

[@gcervantes-]

I like how you have the steps written down and it's clear! My instructor doesn't have it clearly written down like this. Thank you so much, this helped a lot!! The 2nd questions algebra is a but confusing for me but I'll get it down.

[@imdisappointedinyouson1487]

love it when he walks you though the equation, you are truly a saint

[@Dagasm]

Your strategy for choosing the right equation has really helped me keep my sanity. I'd like to see the problem worked out onscreen though so what we're seeing isn't just the populated equation followed by the answer.

[@Vigilante2011]

Dang, I've been searching for a clear explanation for this concept, and so far, your video was the only one that made sense to me. So, thanks!

[@PhysicsclassroomVideos]

Glad it worked for you. You might find the Calculator Pad practice problems on the website to be a useful follow-up.

[@Vigilante2011]

@@PhysicsclassroomVideos Thanks! will look into it.

[@lloydlontok1991]

better than my teacher explanation, cheers😇

Bruh, I tried solving this without a calculator. My brain died after getting this far before realizing I have to go to bed and that calculating this many things including exponents and division was simply to much right now, Great video, I understood all the concepts without ever taking algebra physics or anything, when I told my school I liked math they put me in the most boring low level math classes because they give the better classes only to kids who went through middle school math. Obviously I dropped out of that garbage. Anyway I got this far without a calculator before deciding it's time to relax and go to bed. D = Vo * T + 1/2 * A * T^2 D - (0 * 3.80s) + (1/2 * 6.52m/s * 3.80^2) D= 0, ((1/2)6.52= 3.26)) 3.80^2 D= 0, 3.26 3.80 * 3.80 = 380x380/100.... 380x380= 380x380/3 = 8/3= 2.666, 2.666x3=8 true 126.666x126.666 126.666x126.666 26.666^26.666=400 +x X= (6.666*26.666) 20x6.666= 66.666+66.666 = 133.222222... There's a lot more I have yet to calculate. without a proper background in mathematics the steps to simplify these problems are quite a lot. To You tube trolls, No I didn't reach the answer yet so don't reply some thing about how I didn't get it right when I didn't even finish the equation. Yes I know the answer already, because I watched the video, Knowing the answer won't help me solve the problem tho.

[@yamiomo3277]

I am realizing more and more how spoiled we are to have calculators and smartphones, Everyone used to do ALL the math's by hand. I thought it would be handy to try learning the basics without help of technology, Then I realize I would be obsolete in most situations doing mathematics by hand when we have algorithms and calculators to solve these problems for us. In some situations, doing the math by hand is the only way, but In those situations Best leave it to an expert in the subject. I admit an expert would probably use the tools available to simplify the parts of the problem that they could to save time. Even still, Maths is hard. and anyone who says otherwise hasn't tried putting down the goddamn calculator.

[@dianabloom8581]

You saved my life, thank you Mr. H!

[@PhysicsclassroomVideos]

I'm glad I could help.

[@ha3537]

this helped me so much. it’s actually so simple my teacher made me so confused

[@will_itspill4462]

Thank you for saving my life

[@melissamelissa6127]

I wish i would have found this video sooner. My professor is a nice guy but a terrible terrible instructor. hopefully you have videos that will explain the material for my next exam

[@PhysicsclassroomVideos]

We probably do have videos for your next exam ... likely vectors and projectiles or Newtons Laws. They are easy to access using links on our website.

[@yyulee]

thank you for the thorough explanation! ☺

[@maryanneheni579]

Thank you for your lecture.. now I have understand how to solve kinematic problems. I'm a student attending National High School of Port Moresby Papua New Guinea.

[@effervescentwave8038]

I’ve been so confused, thank you for this clarification!

[@PhysicsclassroomVideos]

I'm glad it helped.

[@mikebanks482]

Am understanding this equations

[@hampterclips]

You just saved my life bro

[@SuperStarArt-eb6dr]

Hello Mr.H , what if the question is asking "determine the stopping distance"? I believe they gave me an initial velocity, a final velocity and acceleration, but how do I find the distance? this is set k13 kinematics equations, question number 3, may you please help me?

[@PhysicsclassroomVideos]

That problem has an Audio Help file that tells you exactly how to solve it. Tap the "head phones"

[@Playereqz]

great video cool man. I will give u a 1000 likes

[@PhysicsclassroomVideos]

Thanks. I'll take as many likes as you're allowed to give.

[@sharonslater4935]

This was really helpful, however, agree with @Dagasm, to show the entire workings of the problem instead of just the populated answer.

[@PhysicsclassroomVideos]

Thanks for the feedback. That will be helpful in future videos.

How is 0.5•6.52•3.8=47.1? This is multiplying, right?

[@PhysicsclassroomVideos]

3.8^2 (squared)

[@sammacpherson3945]

How did you get 47 in the first problem? I was able to do everything but when it came time to solve the equation I'm getting everything but 47.1.

[@blaisearchiea.aranzado7896]

if m/s²÷m/s² the answer would be m only right?

[@PhysicsclassroomVideos]

Nope. (m^2/s^2)÷(m/s^2) = m Note the additional ^2 in the numerator ... which might be what you meant.

[@leasibomit4315]

Good day! I would like to have clarification in example number 2

[@leasibomit4315]

I calculated (32)² which is 1024 minus 9.6 equals 1014.4 divided by 22 on the other side equals to 46.11

Hhmmm what did I fail to calculate?
