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

Anyone can explain this answer please?

In sliding more surface area is used means more friction and more loss to the object means damaged.
But in sliding less surface area or move along only one axis therefore less friction.

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

In sliding friction whole part of the body is contact with the surface whereas in rolling friction only one part of object is in contact when the body is in motion.

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

Why its vice versa is not true?

In sliding surface comes into contact while in rolling either point or line contact occurs between surface.

In sliding we have to apply more force to crush the irregularities interlocking between the two objects for example rubbing two sandpaper against each other.
While in rolling irregularities are not crushed beneath this irregular surface just roll over the other like a gear system and provide less friction and force to move.

Frictional force in sliding > frictional force in rolling.
Because surface area of sliding will more than the rolling.
So, friction can be reduced by changing from sliding to solid.
