Rotational Dynamics: The Simple Yo-Yo Problem

[@KukkiLover]

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

[@physicsi-problems7043]

These videos are pure gold

[@farhadkvolley]

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

[@harunresulcan9666]

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

[@donia4799]

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

[@PhysicsNinja]

You’ve got this. Good luck tomorrow

[@YOK-l9b]

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.

[@zachrisheq9083]

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

[@aaronnikels5706]

Thank you man, you're such a life saver

[@nathangrueber9834]

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

[@aditya_saha]

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

[@PhysicsNinja]

Yes, depending on the pivot location the weight can produce torque

[@alixzandrazabal]

This helped tremendously, thank you.

[@dagmarski4133]

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?

[@PhysicsNinja]

If there’s no slipping the is no work done by tension. If like an object rolling on the ground except vertical.

[@dagmarski4133]

@@PhysicsNinja oh I see, thank you!

[@destdrom]

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

[@lexced16]

Thank you.

[@boboganbobogan9297]

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

[@rohitburra3337]

This is why I chose to go to culinary school😂
