Question

Long Answer
Explain the action of rollers in reducing frictional force.
​

Answer 1

Answer:

No force is transferred or modified by a rotating wheel. Instead, a rotating wheel can make work easier by reducing the friction between an object and the surface over which it moves. A wheel reduces friction by allowing the contacting surfaces to roll rather than to drag or slide over each other.
