The force of sliding friction is large and difficult to affect while the force of rolling friction is smaller and easier to overcome.
Rolling friction is less than the sliding friction because the area of contact is smaller in rolling friction than in sliding friction.The main advantage of this is that we can reduce the friction between the bodies which are sliding over each other by replacing the ball bearings and rollers.
Hope you mean rolling friction and sliding friction. Sliding friction will be more compared to that of rolling friction.
rolling to sliding
Because when the object is rolling, lesser area of its surface is in contact with the other surface.
There are two kind of Frictions: 1 Sliding friction 2 Rolling Friction sliding friction> rolling Friction.
Converting sliding friction to rolling friction reduces the amount of friction felt on the system.
Rolling friction generates considerably less heat than sliding friction. .
With rolling friction, the rolling object is not rubbing against anything, unlike sliding friction.
due to the less surface area rolling friction is lesser than sliding friction
The rolling friction is slightly less than the sliding friction because of the limiting forces.
