Question

What are the factors on which coefficient of friction depends?

Answer 1

Coefficient of friction:

The coefficient of friction is defined as the ratio of the force of friction acting between two objects and the force which is pushing them together. The value of the coefficient of friction varies from zero to one.

There are two types of coefficient of friction:

1. Static coefficient of friction
2. Kinetic (also known as sliding) coefficient of friction.

Factors on which coefficient of friction depends:

The coefficient of friction depends on the nature of the surface. Static friction does not depend upon the area of the surfaces in contact because it only depends upon the nature of the surfaces of the material.

Therefore, the coefficient of friction is a measure of the amount of friction existing between two surfaces.
