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 .

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 2 жыл бұрын

When PE=0, the term mathematically cancels.

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

Because the car is zero height above the ground.

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!❤

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