Q:

# Can the coefficient of friction ever be greater than 1?

A:

The coefficient of friction can be greater than one. The coefficient of friction relates the normal force of an object on a surface to the friction force between the object and the surface.

The friction force on an object is calculated by multiplying the coefficient of friction, static or kinetic, with the normal force on the object. Though the coefficient of friction is generally less than one, some object/surface combinations can have higher coefficients of friction, such as rubber on rubber. A coefficient of friction greater than one implies that the friction force on the object is greater than the normal force.
