What is Viscous Force?

The viscosity of a fluid is a measure of its resistance to deformation at a given rate. For liquids, it corresponds to the informal concept of "thickness": for example, syrup has a higher viscosity than water. The viscous force is the force between a body and a fluid (liquid or gas) moving past it, in a direction so as to oppose the flow of the fluid past the object.

What is Kinematic viscosity?

The kinematic viscosity is defined as the absolute viscosity of a liquid divided by its density at the same temperature.
