### 11.1 Rolling Motion – University Physics Volume 1Explore further

From (a), we see the force vectors involved in preventing the wheel from slipping. In (b), point P that touches the surface is at rest relative to the surface. Relative to the center of mass, point P has velocity, where R is the radius of the wheel and . is the wheel's angular velocity about its axis. Since the wheel is rolling, the velocity of P with respect to the surface is its velocity ...
