I assume this relates to a wheel.
When the wheel is rolling, the surface of the wheel is not moving relative to the surface of the road when they are in contact. however, the wheel deforms slightly and because of this, the normal force slightly opposing the motion of the wheel rather than simply pushing it up. This is rolling friction or more commonly known as static friction.
When the wheel is sliding, the wheel is sliding over the road's surface, meaning that there is relative movement between the wheel and the road. this is known as sliding friction or kinetic friction.
sliding friction
due to the less surface area rolling friction is lesser than sliding friction
sliding friction
There are four types of friction: Fluid Friction (The friction caused by falling through air or water, or any other liquid etc), rolling friction (Like a ball rolling across the floor), static friction (The force it takes to begin something's movement), and sliding friction(Like pushing a box across the floor). In order of strongest to weakest it's Static, Sliding, Rolling, Fluid.

Rolling friction generates considerably less heat than sliding friction. .

Generally, sliding friction is much stronger than rolling friction.
== == AnswersIt is easier to stop sliding friction than rolling friction. The force due to sliding friction will always be greater than the force due to rolling friction. And since friction force will be in the opposite direction of motion it will be easier to stop an object in motion that is sliding than one that is rolling.
