Detailed explanation-1: -The force that prevents the relative motion between the layers of a liquid is called the viscous force.
Detailed explanation-2: -The property by virtue of which a liquid opposes relative motion between its different layers is called viscosity.
Detailed explanation-3: -Viscosity refers to a material’s ability to resist displacement between its layers. Also known as viscous force, it is the force that opposes relative motion between the layers.
Detailed explanation-4: -Viscous force is a frictional force which opposes the relative motion between liquid molecules.
Detailed explanation-5: -More precisely, Viscosity is the property of a fluid by virtue of its offering resistance to the movement of one layer of fluid over an adjacent layer. The viscous force is the force acting across layers and counteracting relative motion.
