a ball rolling across the floor ( a flat surface) you rolling down a hill rocks rolling down hill etc. hope this helped ronkkiki
Opposite its motion.
Friction is one force causes a ball to roll downhill. The smaller the static friction coefficient, the more liable the ball will be to skidding instead of rolling. Static friction is involved in a ball rolling downhill.

A wheel is an example of rolling friction. An example of rolling friction would be if you took kyle leary and folled him down a hill. his fat touching the grond would create rolling friction

rolling an electric ball down a hill with a magnet at the bottom
It involves the forces of Gravity. It also involves Friction and Inertia.
Say you are driving a car or riding a motorcycle and you just remove you foot or hand from the accelerator. What will happen? After some time depending on your velocity, the vehicle will stop. Why? Consider your entire vehicle an ideal system meaning that no part provides any sort of friction. Now consider road, road is rough and will definitely provide friction. Since your vehicle's tires are rolling against the road, the road will provide friction in the direction opposite to that of your vehicle's motion. In real situations, both tire and road will contribute to the rolling friction.
If you push a rollerskate down the sidewalk and don't keep pushing it, rolling friction will eventually cause it to stop on its own (assuming that the sidewalk is level and not on a hill)
if there is friction on the hill it will slow you down
