coefficient of friction

[¦kō·ə′fish·ənt əv ′frik·shən]
(mechanics)
The ratio of the frictional force between two bodies in contact, parallel to the surface of contact, to the force, normal to the surface of contact, with which the bodies press against each other. Also known as friction coefficient.

coefficient of friction

The ratio of the force causing a body to slide along a plane (in the direction of sliding) to the normal force pressing the two surfaces together.
