Friction only acts to oppose relative motion or the tendency of motion.

Vedclass · Answer

(B) Friction is a resistive force that acts only when there is relative motion or a tendency for relative motion between two surfaces in contact.If a ball is at rest on a horizontal surface and no external force is applied to it,there is no tendency for the ball to move.Therefore,the net force acting on the ball is zero,and the frictional force remains zero.Friction does not initiate motion on its own; it only opposes the motion caused by an external force.

Why does friction not roll a ball backward if no external force is pushing or pulling it?
