Question
Which force is acting here?
- Static friction
- Sliding friction
- Rolling friction
- Fluid friction
Hint:
The frictional force created when an object is rolling over a surface is rolling friction.
The correct answer is: Rolling friction
Rolling friction force is acting here.
- The friction force formed when an object rolling over a surface is rolling friction.
- Rolling friction refers to a type of kinetic friction which is the resisting force that opposes the motion of a rolling body.
- It resists the motion of an object from rolling.
- For example: The ball rolling on a surface has rolling friction.
