People say that marbles experience friction when rolling across a surface,but i don't get why. The dynamic and static friction don't seem to fit here and the point is that it have a very little contact with the surface. Note that its not rubbing across the surface but rather rolling across it. You might give an example of the bowling ball,but the force used is to push it across the floor and not the kind of force to roll and ball and thus the bowling ball slides and causes friction. I really don't get why a marble experience a friction. HELP!
