Question

explanation and example for rolling friction​

Answer 1

Answer:

The amount of friction created by a rolling object is less than the friction created by normal force. It is dramatically less than other types of friction, such as sliding friction.

There are various factors that can affect rolling friction such as:

Shape of wheel

The type of surface on which the wheel is rolling

Any movement of the surface or below the surface

Original speed of the wheel

Diameter of the wheel

Amount of pressure on the wheel

Adhesion of the surface

Any amount of sliding that occurs in addition to the rolling motion

Deformation of object or of surface

Over inflation of tires

Micro-sliding

Thickness of tread on tires

Shape of tread on tires

Material that wheel or ball is made of

Everyday Examples of Rolling Friction

A car will eventually come to a stop if just allowed to roll as the friction between the road surface and the wheels causes friction that causes the vehicle to stop.

Bike wheels that are thicker will lessen the potential speed of the bike because there is a greater wheel surface to create friction against the surface which will slow the bike.

Heavy duty trucks get greater gas mileage when tread begins to wear on the tires because there is less rolling friction, allowing the truck to move more quickly with less resistance.
