• 1 12. Rolling, Torque, and Angular Momentum

H We need to find the torque that makes the disk start rolling. Consider the rotation around the center of mass: • The force of gravity acts at the center of mass and hence produces no torque. • The normal force has zero level arm and hence produces no torque. • The force of friction provides the torque!

• Rolling Friction by Ron Kurtus - Physics Lessons: School ...

Rolling Friction / Rolling Resistance. by Ron Kurtus (revised 15 November 2016) Rolling friction is the resistive force that slows down the motion of a rolling ball or wheel. It is also called rolling resistance.. When a force or torque is applied to a stationary wheel, there is a small static rolling friction force holding back the rolling motion.
