Do you want to know why your hand becomes warm or why the wheel slows down?

I red the sentence in the chapter of Heat, what is the meaning of this sentence.

anonymous · Answer

Force of friction, rolling resistance, kinetic energy, sound energy, shear forces, etc.. there's a bunch of stuff going on when you put your hand on a wheel in order for it to stop.

anonymous · Answer

Yeah I think it is a type of change of friction force to the heat. because friction forces are non-conservative
