This video is underrated af. Great explanation, thx

[@vuquangminh3033]

can u explain for me why the torque=+fs.R but not -fs.R because it is opposite the chosen direction

[@sch0les]

@@vuquangminh3033 because torque isnt in the x y plane, but theres only two directions, clockwise or counterclcockwise, since friction is clockwise it is positive

[@kevinyuan5232]

actually so helpful! thx!

Thank you so much

I love this

[@elo_memes]

thx sir 🙂

[@MDB28]

Is the case is same for a rolling sphere /cyllinder sir??

[@a.s.l711]

what does slipping actually means in physics?

[@edgardchow]

no/negligible friction; without friction there is no force exerting a torque on the object and therefore it does not rotate. think of how cars slip on ice because there is not enough friction for the tires to grip the ground and rotate
