APFIVE Rotational Motion and Kinetic Friction
A disk with radius R is spinning with angular velocity ω when it is placed on a rough horizontal surface. If the disk initially has no translational velocity, what physical process explains why the disk will eventually move with a non-zero translational velocity?
A
Gravitational potential energy is converted to motion
B
Friction converts rotational energy to translational KE
C
Air resistance pushes the disk forward
D
The normal force creates a torque that propels the disk
