you got me a 5 in both AP Physics 1 and AP Physics C Mechanics, just came to say thank you.

Very helpful, I'm studying for my finals and this video honestly made me solve lots of problems immediately. Thanks

[ghstGD]

thank you this helped me better understand the hardest topic thus far in AP physics 1

7:02 you can tell who DOESNT like roller coasters.

Thank you for this video, but may I ask why do you feel you weigh less on the top of the hill? If the normal force is less, then that means the force of gravity is more than the normal force, so you should feel as if you weigh more because the force of gravity is larger, right? Please correct me if I am wrong. Anyway, your channel is amazing !!!!

Why don't you consider static friction in this problem? In the mint problem in your other video, you had kinetic friction in your force diagram, but it's not here-- why not/

I have doubt in another kind of uniform circular motion of a car. If a car makes a curve on a level road which force will act as the centripetal force?

But if we are rotating on the planet Earth that means that the normal force and weight are never really the same? There is always a centripetal force due to a gravity that will make the difference between our weight and normal force?
