Question

What is the coefficient of friction?

Answer 1

1. The force that keeps objects from freely moving against one other is known as friction.
2. The coefficient of friction is defined as the ratio of the frictional resistive force to the perpendicular force that pushes the objects together.
3. The coefficient of friction can be written as: $\mu =\frac{F}{N}$ where $\mu$ is the coefficient of friction, $F$ is the frictional force, $N$is the normal force
4. The coefficient of friction (COF) is a one-dimensional quantity that represents the ratio of friction and normal forces.
5. COF is determined by the type of materials and the roughness of the surface.
