Explain why sliding friction is less than static friction?

Question: Explain why sliding friction is less than static friction?

Sliding friction is generally less than static friction because the surfaces of two objects in motion have less time to interact and create interlocking contact points compared to surfaces at rest. When two stationary objects are in contact, the weight and normal force of the objects press their surfaces together, creating strong interlocking contact points that require a large amount of force to overcome. However, when the objects are in motion, the surfaces tend to slide over each other more easily because the interlocking points are fewer and less well-established. As a result, less force is required to maintain the motion of the objects, resulting in less sliding friction.
