If a body is sliding or moving on the other body (surface) means it creates friction with the surface, sliding on the surface means the body cannot revolve on its axis and it means that is rubbing over the surface, rolling means the body is revolving along its horizontal axis in contact with the surface.

Describe Sliding in detail.

It's simple that which converts sliding friction into rolling friction. Eg: (hard steel balls) placed between moving parts which converts sliding into rolling.

It is Based on contact with the area.

How can we reduce friction from sliding to rolling?

But on rolling a frictional force will be acting on the body thereby, resisting its motion. Whereas sliding can take place if there is a less frictional floor.

Good information, Thank you all.

Friction doesn't depend on surface area.

Adarsh said:   9 years ago
Coefficient of friction for rolling is a far less than that of sliding. And static state doesn't mean no force is applied on body. Friction is there to resist force.

Pragati said:   1 decade ago
Rolling friction is the resistance to motion experienced by a body when it rolls upon another. It is much less than sliding friction for same pair of bodies. When one body rolls upon another, there is theoretically no sliding or slip between them. And if both are perfectly rigid, there is no surface of contact.

Answer is wrong:

D would be correct. Friction can be brought to zero if we change the object from dynamic to static position. D would be more appropriate than A.
