More the surface of contact more will be friction sliding involves large surface contact than rolling.

Why cannot be potential energy to kinetic energy and dynamic to static friction please explain?

Well said @Santosh. It is all about the point of contact versus the axis of rotation.

Rolling has point contact between the two actual condition of the motion points.

Any object rolls when there is no friction. So, Sliding to Rolling is correct.

Akshay said:   1 decade ago
Coefficient of rolling friction is always less than that of sliding friction.

Vjsjs said:   8 years ago
Its wrong because it an object is static it has 0 friction so answer is D.

Sliding has one direction but rolling has many direction to take flow.

To applying the slow moment of force to it, then it is in fast motion.

Thanks for such understandable explanation with examples.
