Question

a short note of rolling friction​

Answer 1

Rolling friction is considerably weaker than sliding friction.Laws of Rolling Friction

There are three laws of rolling friction:

With the increase in smoothness, the force of rolling friction decreases.

Rolling friction is expressed as a product of load and constant to the fractional power.

F = kLn

Rolling friction force is directly proportional to load and inversely proportional to the radius of curvature.

F=μ×Wr

Answer 2

Answer:

Rolling resistance sometimes called rolling friction or rolling drag ,is the force resisting the motion when a body rolls on a surface another cause of rolling resistance lies on the slippage between the wheel and the surface , which dissipates energy
