For 10 points, name this force that opposes the motion of an object, caused by two surfaces rubbing together.
Amontons' laws govern this phenomenon. Relations for the dry form of this phenomenon were first explained by Coulomb. This phenomenon results in the change of kinetic energy into heat. The magnitude of this force equals the magnitude of the normal force times this force's namesake coefficient, which is symbolized mu and comes in static and kinetic varieties.
