Answer:

What is Rolling Friction?

For a moving solid body, there are two principal types of friction that act upon it:

The force resisting the motion of a rolling body on a surface is known as rolling friction or rolling resistance. Rolling of ball or wheel on the ground is an example of Rolling friction.

The other type of friction is sliding friction. In this type of friction, there is a restriction on the body’s movement as only one side of the body is in contact with the surface. Pushing a box across the table is an example of Sliding friction.

Rolling friction is considerably weaker than sliding friction.

Explanation:

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 = kL n

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