Fluid friction describes the friction between layers of a viscous fluid that are moving relative to each other. [7] [8] Lubricated friction is a case of fluid friction where a lubricant fluid separates two solid surfaces. [9] [10] [11] Skin friction is a component of drag, the force resisting the motion of a fluid across the surface of a body.

While it is true that increased pressure, such as that exerted by someone standing on a sheet of ice, will lower the melting point of ice, experiments show that the effect is too weak to account for the lowered friction. Materials scientists still debate whether premelting or the heat of friction is the dominant cause of ice's slipperiness ...

The regions of higher friction along a fault plane, where it becomes locked, are called asperities. Stress builds up when a fault is locked, and when it reaches a level that exceeds the strength threshold, the fault ruptures and the accumulated strain energy is released in part as seismic waves , forming an earthquake .
