It is known that polishing a surface beyond a certain limit increases rather than decreases the frictional forces. Explain. ?

Text Solution

Verified by Experts

When the surfaces are polished beyond a certain limit, the molecules exert strong attractive forces on each other. This is called surface adhesion. 1 overcome these forces, additional forces required. Hence, the frictional force increases.
