On an atomic scale, this property may be explained by either of two models in which it is mediated by phonons: the dislocation model, and one proposed by Tomlinson.

It may be measured by an atomic force microscope or a tribometer. Darcy and Weisbach name a factor for determining it for fluid flow through a pipe, and this type of force is completely dominant at extremely low Reynolds numbers. According to (*) Amonton's laws, this force is independent of the apparent area of contact between two objects. It is responsible for damping oscillations, and in free fall, when this force balances an object's weight, that object falls at its terminal velocity. For 10 points, identify this non-conservative force which acts opposite to the direction of an object's motion, with a coefficient symbolized by "mu."
