Why the friction can be smaller than the force? What determines the friction? And how does a disk rotating on a horizontal surface with friction come to terminal when it rotates without slipping and static force does not turn the kinetic energy into heat?
Homework Statement
A horizontal force is exerted on a uniform disk towards the center of mass resting on a horizontal table. The surface has friction. How does the disk begin to move ? Because when the force increases from zero, at first the friction is static friction which means the net...
