Question

Define rolling and fluid friction​

Answer 1

Friction is the force that opposes motion between any surfaces that are in contact. ... Static, sliding, and rolling friction occur between solid surfaces. Fluid friction occurs in liquids and gases.

Answer 2

Answer:

1. rolling friction comes into play when an object rolls over the surface of another object rolling friction is much less than sliding friction this fact lead to invention of wheels which in turn lead to a revolution in transportation
2. flirt also exert frictional force on the objects moving through them this force depends upon the nature of the flood the shape of the moving object and the speed of the moving object with respect to the flood
