dynamic friction

dy·nam·ic fric·tion

the force that must be overcome to maintain steady motion of one body relative to another because they remain in contact. Compare: starting friction.

friction

the force between the surfaces of two objects in contact, at least one of which is moving (or tending to move) relative to the other. kinetic friction friction due to motion of one object relative to another; also known as dynamic friction. coefficient of friction dimensionless (no units) number representing friction between two bodies or objects. Calculated as the force parallel to the object or surface (tangential force) divided by the force perpendicular to the object or surface (normal force).
