Question

How does friction depend upon the nature of the surfaces in contact?

Answer 1

smoothness

Friction depends on the nature of surfaces in contact. For a given pair of surfaces, friction depends upon the state of smoothness of those surfaces. The force of friction is greater if a rough surface is involved. Friction is caused by the irregularities on the two surfaces in contact
