Question

3. How does friction depend on the nature of surfaces in contact​

Answer 1

Answer:

Friction depends partly on the smoothness of the contacting surfaces, a greater force being needed to move two surfaces past one another if they are rough than if they are smooth. ... It does, however, depend on the magnitude of the forces holding the bodies together.

Answer 2

Answer:

The force of friction depends on the nature of the surfaces in contact. The force of friction depends upon the irregularities present on the surface of the object. if the object has irregularities on its surface i.e. the surface is rough then the force of friction would be more .
