WebApr 4, 2024 · Static friction can be defined as a force that resists the movements of an object along the path. Lastly, understand it with a simple example. Consider the … WebFriction. The force of static friction does no work on an object at rest and you do no work against this force. Even though you may be pushing hard against an object acted on by the force of static friction, the object is not moving. The displacement is zero and W = 0. You, however, do work against the force of sliding or kinetic friction.
