Question

Define rolling friction and give an example where rolling friction comes into play .

Answer 1

Hey mate

Here is your answer
When a body slides(moves with all its surface area in contact) over another body, the resistance faced is due tosliding friction. On the other hand if a body rolls (moves with just a single point of its surface in contact) over another body, the resistance offered is a case of rolling friction

Answer 2

Answer:

Rolling friction may be defined as, “the force resisting the motion when a body, such as a ball or a wheel, rolls on a surface.”

Rolling friction comes into play when heavy objects are needed to be moved from one place to another and are made to roll over a surface.

E.g. are heavy furniture’s that are facilitated with wheels to reduce the effort required to move them from one place to another.
