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

Solution
Friction comes into play when irregularities present in the surfaces of two objects in contact get interlocked with each other.
The sliding friction is less than static friction because of the interlocking of irregularities in the two surfaces is less when two surfaces slide over each other.
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.
