viscosity
(Also called internal friction.) The transport of mass motion momentum solely by the random motions of individual molecules not moving together in coherent groups.
Viscosity is a consequence of gradients in velocity fields in fluids. Sometimes described as fluid friction because velocity gradients in fluids are damped as a consequence of viscosity.
