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

Friction between the two types of contact rolling & slides but they moving on what type of area that's details may be help like water hill.

This is because more of the body comes in contact with the surface than when rolling. Therefore while sliding friction is increased.

It is done because of contact area which used in sliding is more then rolling. In rolling motion only point contact have been done.

Since rolling friction is smaller than sliding friction, it helps reduce the amount of friction between two surfaces in contact.

Sliding has an one direction for flow but rolling has many direction to take flow, so opposing force will be reduced.

Slidng: area of contaCt is more (greater friction).
Roling: area of contact becomes much less (lower friction).

Gowtham said:   7 years ago
The friction is increased on the sliding object at the time the sliding force is converted to rolling process.

Sliding consist more friction than rolling. Because it has sliding consist large contact surface than rolling.

Brish said:   1 decade ago
In sliding surface comes into contact while in rolling either point or line contact occurs between surface.
