Question

Unit of Co-efficient of friction is
​

Answer 1

Answer:

The coefficient of friction is dimensionless and it does not have any unit.

Explanation:

It is a scalar, meaning the direction of the force does not affect the physical quantity. The coefficient of friction depends on the objects that are causing friction.

Answer 2

• The friction coefficient, often known as the coefficient of friction, is a dimensionless quantity whose size indicates how easily two solid things pressed together may initiate or maintain relative motion.
• As it is the ratio of two forces operating perpendicularly and parallelly on the interface between the contacting bodies, the friction coefficient has no dimensions.
• So, the unit of coefficient has no unit.
