Question

Explain Why the sliding friction is less than the static friction?​

Answer 1

The friction between the two surfaces is because of the interlocking of the irregularities of the two surfaces. During sliding, contact points do not get enough time to get interlocked properly. ... This explains why sliding friction is less than static friction.

Answer 2

Friction occurs when two bodies slide across each other or try to glide across each other. It always seeks to stop movement by acting in the opposite direction of the applied force.

Explanation:

• It occurs as a result of surface roughness, deformation, or adhesion. When there is no relative motion between the two bodies, static friction occurs, and when there is relative motion between the two bodies, sliding friction occurs.
• Because the surface irregularities are in touch for shorter periods of time when a body is moving, there is less friction. Due to inertia, a moving body tends to stay in motion. As a result, static friction is less than sliding friction.
