Question

Why is sliding friction lesser than the static friction?

Answer 1

When an object has already started moving ,the irregularities on its surface do not get enough time to lock into the irregularities on the surface of the other object completely. Since the interlocking of the two surfaces is less when an object has already started moving, therefore, the sliding friction is lesser than the static friction.

Answer 2

Answer:

Friction is defined as the force that opposes the motion of a solid object over another. The sliding friction and static frictions are a type of friction.

Sliding friction – Sliding friction is defined as the resistance that is created between any two objects when they are sliding against each other.

Static friction – Static friction is defined as the frictional force that acts between the surfaces when they are at rest with respect to each other
