Rotational Dynamics: The Simple Yo-Yo Problem 

This was such a concise explanation. Thank you so much!

These videos are pure gold

Hey, thanks so much for putting the time and effort in here! It really saved me time on my physics project-

Watching this the night before my physics exam lol i love your explanation

What a pure explanation. Why is this video has only 1.5k ?

Thank you man, you're such a life saver

your making physics so easy dude holy shit i was stuck on this for so long

How can you choose to define Weight as positive 3:23 but if you don’t you get it wrong?

A rolling disc from a slope also has the same expressions. I guess it shouldn't be the coincidance since the initial energy is shared by linear motion and rotational motion in the same way.

how can we prove that when object rotates without slipping v equals omega times radius?

if it is pure rolling at the point of contact, should the weight contribute to torque

Calculate the center of rotation? Of mass? There is no center. Its pushed directly right angles to the center of rotation like an axle would be creating horizontal rotational torque

This helped tremendously, thank you.

Thank you.

Great explanation! There’s one thing I don’t understand, what happens with the Work (T*h) the tension gives? Shouldn’t this be in the conservation of energy formula?

This is why I chose to go to culinary school😂
