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

[@klowihsot]

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!

[@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.

[@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

[@nobodyreallyknowsdothey]

i’m watching a bunch of these videos last minute will let you know how the test goes

[@wulfgang4520]

Man is gone, the test sent him to the shadow realm.

[@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.

[@domstaruc-hw3gi]

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

[@PhysicsclassroomVideos]

I'm glad you found it 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 .

[@theodddude9599]

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

[@user-rn6kh8oc1d]

Thank you

[@JuliuSsenabulya]

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

[@robbymurray2560]

got a test in 2 hours thanks man really helpful

[@brainzstorming1007]

THIS IS THE BEST !!!!!, REVIEWING FOR MY MIDTERM EXAM AND THIS ADDITIONAL INFO'S HELP MEEE

Wonder Full explained

[@arsemaesubalew1508]

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

[@2dogs1tale81]

I found this quite helpful. Thx

[@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.

[@constancelukwesa5085]

Thank you do much sir yove built my confidence in physics

[@myakkyyy]

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

[@PhysicsclassroomVideos]

You're welcome. I'm glad it helped

[@lawrencesafranek3530]

this helped tremendously… thank you!

[@PhysicsclassroomVideos]

Thanks for your kind words.

[@user-rn6kh8oc1d]

Wonderful explanation

[@PhysicsclassroomVideos]

I am glad that it worked for you.

[@yuiioxoxx]

useful!! thanks a lot!

[@ronnie6162]

This helps me a lot! thankyou

Thank you sir

[@MDAviaton]

Thanks for the video

[@sphiix2258]

thank you 🎉🎉

[@kundaemma9073]

Thank you,

[@therealab7928]

thank you Mr.H!

[@PhysicsclassroomVideos]

My pleasure!

[@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?

[@robertjackson8270]

Sir, thank you for your help. İ liked video

[@Urawizardharryy]

thank you

[@johncina621]

Thank you so much sir !

[@PhysicsclassroomVideos]

You're welcome.

[@rasuru_dev]

thank you!

[@PhysicsclassroomVideos]

You're welcome!

[@shivprasadtiwari4857]

A wonderful lecture 😁 it helped me thank you sir

[@PhysicsclassroomVideos]

Thanks for your kind words.

[@bizarrecentral6032]

Thanks 🙏

[@PhysicsclassroomVideos]

Youre welcome.

[@test.5]

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.

[@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.

[@matthchuw1796]

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.

[@constancelukwesa5085]

Whre can i find the description

[@JayEulisesAErong]

what happen to cos180?

[@PhysicsclassroomVideos]

It's -1

[@wilmerpena2355]

bro im so lost

[@JuliuSsenabulya]
