Difference between Sliding and Rolling Friction

Distinguish, differentiate, compare and explain what is the difference between Sliding and Rolling Friction. Comparison and Differences.

S.No.	Sliding Friction	Rolling Friction
1	It is the force of friction acting between two bodies which slide or surfaces which are rubbing against each other.	It occurs when the surface of one body is rolling against the surface of another body.
2	Rolling of the bodies over others actually reduces the friction.	Sliding of the body increases the friction. Hence sliding friction is always larger than rolling friction.
3	It acts as a back-haul external force along the contact area to stop the relative motion.	It is a force which attempts to stop the rolling motion by generating a reverse torque and so, rolling friction is a resistive force but not a type of friction.
