5.2 Rolling Motion

When a rigid body rotates about an axis, and the axis itself undergoes translational motion then the combined motion of the rigid body is called rolling motion.

Consider the rigid body of a circular cross- section as shown, with an instantaneous angular velocity 'w' and an instantaneous linear velocity of the center of the mass of  the body 'v';  then   v = Rw and similarly a = ra.
