Question

define rolling force​

Answer 1

Answer:

When an object rolls over the surface of another object ,the resistance to its motion is called rolling friction. It is always easier to roll than to slide an object over another object.So rolling friction is much less than the sliding friction

Answer 2

Explanation:

When one body rolls over the surface of another body, the resistance to its motion is called the rolling friction. Rolling reduces friction. It is always easier to roll than to slide a body over another. That is the reason it is convenient to pull the luggage fitted with rollers.
