Question

Explain why sliding friction is less than the static friction?

✓

Answer

We know that friction is caused by the interlocking of irregularities in the two surfaces.
In case of static friction, interlocking between two objects is very strong but in case of sliding friction, there is a less time of getting interlocked with each other. Thus, the sliding friction is less than the static friction.
