Why sliding friction is slightly smaller than static friction?

The friction is due to 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 slightlylless than the static friction

Hi friend,
This is so because when we move an box it starts sliding, the contact points which are on its surface don't get enough time to lock between the box and the floor. So the sliding friction is smaller than the static friction and we also feel easy to move box when it is already in motion because it is locked with contact to the ground.
Hope it helps....
