Which frictional force is acting here?
- Static friction
- Sliding friction
- Rolling friction
- Fluid friction
Hint:
The frictional force created by the rolling of an object is rolling friction.
The correct answer is: Rolling friction
The frictional force acting here is rolling friction.
- The frictional force formed on a rolling object is rolling friction.
- It resists the force created by a rolling object over a surface.
- Eg. the rolling of a ball on the ground causes rolling friction.
