Difference Between Rolling And Sliding Friction
The differences between rolling friction and sliding friction have been listed in the table below:
|
Rolling friction |
Sliding friction |
|---|---|
|
The use of a rolling motion allows for the avoidance of the use of the friction. |
Frictional sliding arises when the surfaces are dragged against each other or not. |
|
Rolling Friction occurs due to deformation of rolling objects. |
Sliding friction occurs due to interlocking of microscopic surfaces |
|
The value of the coefficient of rolling friction is determined by the radius of rolling body, as well as how much it depress, and the hardness of the surface. |
The value of sliding friction coefficient depends on the real surface roughness and might be affected by the temperature to some degree. |
|
Coefficient of rolling friction: Fr = μrN |
Coefficient of sliding friction: Fk = μkN |
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.
