WebJan 25, 2007 · Yes, friction is an external force. But as long as there is no slipping, the static friction does no work and thus does not affect the mechanical energy. Note that when the sphere is rolling along a horizontal surface, the static friction is zero. Friction is only needed to change the rotational motion, as when the sphere rolls down an incline. WebIn rolling motion without slipping, a static friction force is present between the rolling object and the surface. Can static friction do non zero work? Answer ⇒ Yes. Static friction can do the non-zero work on the object. Does static friction do negative work?
