Answer 1

Hey mate here is the answer


The sliding friction is less than static friction because of the interlocking of irregularities in the two surfaces. When the object starts sliding the contact points on its surface, do not get enough time to lock into the contact points on the floor. So the sliding friction is slightly less than the static friction.


I hope it will help you

Answer 2

Answer:

When irregularities present in the surfaces of two objects in contact get interlocked with each other, friction come into play. The time given in sliding for interlocking is very small. Thus, interlocking is not strong. Therefore, less force is required to overcome this interlocking. Due to this reason, sliding friction is less than static friction.
