Question

5 characteristics of rolling friction​

Answer 1

The five characteristics of rolling friction is as follow:

• The rolling resistance is also called a rolling drag.
• It is defined as a force resisting the motion of a body which rolls on the surface.
• Rolling resistance is expressed as coefficient times the normal force.
• The "cause of rolling resistance" lies in the slippage between "the wheel and the surface".
• The "coefficient of rolling resistance" is generally very smaller than the "coefficient of sliding function".
