What is Rolling Friction?
Rolling friction is a type of friction, that opposes the motion of rolling objects. For example, if a ball is rolling on the floor, eventually it will stop. This happens because the ball is going to experience resistance in the direction of its motion. The frictional force acts on the ball, which is opposite to the motion of the ball and slows down the ball. The deformation of surfaces is the reason for rolling friction. Rolling friction is valid in the case for ball bearings-car tires, bowling balls, etc.
Rolling Friction Examples
Here are some examples of rolling friction
- Wheels of Vehicles: When vehicles move forward, they experience resistance to their motion due to contact with roads.
- Ball Bearings: Ball Bearings uses small metal balls, which creates rolling friction between wheels and axles
- Luggage Wheels: Trolleys use wheels that experience rolling friction when dragged on the surface and help to move heavy luggage with ease.
- Conveyor Belts: Conveyor belts at airports and metro stations are used to scan luggage. In these, rolling friction acts between the belt and the roller.
Rolling Friction
Rolling Friction is a frictional force that opposes rolling objects. Rolling friction is applicable where the body moves along its curved surfaces. For example, wheels in vehicles, ball bearings, etc. are examples of rolling friction.
In this article, we will learn about rolling friction, its definition, laws, formulas, causes, coefficient, and the factors that affect it. We will also learn how rolling friction is different from sliding friction.
