Question

why the visocous force dissipative

Answer 1

Answer:

Viscous forces in a fluid are proportional to the rate at which the fluid velocity is changing in space; the proportionality constant is the viscosity. Viscous Forces Here the frictional force increases as the first power of the relative speed between the surfaces and opposes the relative motion.
