Question

what is the coefficient of friction

Answer 1

A coefficient of friction is a value that shows the relationship between the force of frictionbetween two objects and the normal reaction between the objects that are involved. It is a value that is sometimes used in physics to find an object's normal force or frictional force when other methods are unavailable.

The coefficient of friction is shown by {\displaystyle F_{f}=\mu F_{n}\,} . In that equation, {\displaystyle F_{f}} is the frictional force, {\displaystyle \mu } is the coefficient of friction, and {\displaystyle F_{n}\,} is the normal force.

Answer 2

or

mu is the coefficient of friction .
