Solving Work-Energy Problems

[@ronaldz4083]

God bless you Mr. H, I have an energy unit test tommorow and was looking for some last minute review. I'm glad I find you!

[@PhysicsclassroomVideos]

I'm glad you found the channel also. Good luck on your test

[@internetuser2947]

Student here, thank you so much for the worked exercises and usefull links! all the best Mr. H!!

[@PhysicsclassroomVideos]

Thanks. I'm glad it was helpful.

10:00 in this question the horizontal component of velocity is the same but due to free fall in vertical direction the velocity is root 2gh and final velocity is horizontal component square plus vertical component square whole underroot .

[@robbymurray2560]

got a test in 2 hours thanks man really helpful

[@KillerSDEV1000]

Thank you so much Mr.H. I have a midterm on tuesday and this saved me!

[@PhysicsclassroomVideos]

I am glad it helped! Good luck on your Tuesday exam

[@xxocchitl]

I have exam later and because of ur vid it finally made me understand this after a week of struggling. Thank you so much!!!

[@PhysicsclassroomVideos]

Glad it helped!

[@Ambica-l8t]

Wonderful explanation

[@PhysicsclassroomVideos]

I am glad that it worked for you.

[@robboredninja]

Studying for 11th grade physics next school year, this is helping a lot! Thanks Mr. H!!!

[@PhysicsclassroomVideos]

So glad it's helping. We'll be here all year. Come back for more help when you need it.

[@CalviNsiku]

He's so calm yet impactful...am gonna definitely remember this during tomorrow's exam

[@itsnataliabtw]

I hope it went well, I have my test next week. 😅

[@yipyiphooray339]

thank you so much for this! By the way, does this work for most energy problems? Which ones, does that equation not help with?

[@myakkyyy]

wow, the explanatations were so clear, thank you kind sir

[@PhysicsclassroomVideos]

You're welcome. I'm glad it helped

[@audreyb1803]

Thank you so much Mr. H! You explained these problems extremely well I feel so much better about physics now :)

[@PhysicsclassroomVideos]

Glad you're getting the hang of it.

[@arsemaesubalew1508]

You are very superb 👌 teacher
Thank you very much for this video
You are typical teacher.

[@Ambica-l8t]

Wonder Full explained

[@domstaruc-hw3gi]

this was the first vid that it make me easier to understand physics

[@PhysicsclassroomVideos]

I'm glad you found it helpful.

[@lawrencesafranek3530]

this helped tremendously… thank you!

[@PhysicsclassroomVideos]

Thanks for your kind words.

[@ronnie6162]

This helps me a lot! thankyou

[@PhysicsclassroomVideos]

Glad it helped!

[@2dogs1tale81]

I found this quite helpful. Thx

[@constancelukwesa5085]

Thank you do much sir yove built my confidence in physics

[@nabbaraju1]

Thank you so much! I just had a question - for some of the questions, you mentioned that since the track/road is level, we can cancel out PE on both sides. Why is that so?

[@PhysicsclassroomVideos]

When PE=0, the term mathematically cancels.

[@yuiioxoxx]

useful!! thanks a lot!

[@JuliuSsenabulya]

And may the Almighty GOD reward you abundantly sir.🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏

[@shivprasadtiwari4857]

A wonderful lecture 😁 it helped me thank you sir

[@PhysicsclassroomVideos]

Thanks for your kind words.

[@johncina621]

Thank you so much sir !

[@PhysicsclassroomVideos]

You're welcome.

[@venkataramanaraogarimella3082]

Thank you very much. An excellent tutorial.

[@PhysicsclassroomVideos]

Thank you sir

[@babelsindex]

this is amazing, do you think you could explain why potential energy final and initial are 0 in the first problem?

[@PhysicsclassroomVideos]

Because the car is zero height above the ground.

[@bizarrecentral6032]

Thanks 🙏

[@PhysicsclassroomVideos]

Youre welcome.

[@sphiix2258]

Hocam allllah razı olsun adamsınzı

[@KrischeaPellas]

Hello, Professor! Can I ask where you get those world problems? From what book? Or did you made those?
Anyway, your channel is really helping me practice my physics class. You're a big help!❤

[@PhysicsclassroomVideos]

I'm not sure. I probably wrote them myself.

[@wilmerpena2355]

bro im so lost
