Hi all:
I am studying the mechanics of a system where there is string wrapped around a massive pulley, and a block at the end of the string.
Correct me if any of this is wrong, but the system (pulley and block) must have the same linear acceleration. So, in the case that the pulley is much more massive than the block, it will require greater torque, and subsequently force to give it the same acceleration.
How is this accounted for? Does the string have different tension around the pulley than it does at the block end?
Isn't it true that Tension= mg-ma because it is exerting upward force on the block?
Thank you for your efforts in explaining this!
Thank you,
