Question:

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

Answer:

Sliding friction is less than the static friction because force of friction depends on the interlocking of two surfaces. In sliding, interlocking between two surfaces is weak, so to overcome this we have to apply less force. But in static friction, the interlocking between the irregularities of two surfaces is very strong. So we can say that sliding friction is less than the static friction.
