Question

Which force is acting here?

  1. Static friction
  2. Sliding friction
  3. Rolling friction
  4. Fluid friction

hintHint:

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.
