Question

4 similarities between viscosity and solid friction

Answer 1

Answer:

Similarities: Both opposes relative motion. ... Viscous force depends on the velocity gradient and area of contact and frictional force independent of area of contact and relative velocity. Viscosity of liquid decrease with increase in temperature, Where as friction independent of temperature.

Answer 2

Explanation:

Friction is a tenure used to refer to forces that oppose the relative motion in general. The property of a fluid for which relative motion between different layers is resisted or retarded is called viscosity. Friction is the force that opposes the motion. It acts between the surfaces in contact. Viscosity is the internal friction of fluid flow. It is the measure of fluid’s resistance to flow. Friction and viscosity refer to forces that oppose the motion. The main difference is; the viscous force depends on the velocity gradient and area of contact and frictional force independent of area of contact and relative velocity.
