Explain why the sliding friction is less than the static friction.

Answer

Friction is caused by the interlocking of irregularities between two surfaces.

When the object is in motion, the irregularities of the moving object doesn't get much time to interlock with the irregularities of the surface.

Since the interlocking is less, the frictional force will be smaller

Hence, Sliding Friction is smaller than Static Friction
