[QUOTE="FurVid, post: 36953, member: 19"] Right, but it doesn't go faster due to the reduced friction, does it? If there is enough friction for the ball to roll with slipping (and as you can see it takes very little), then the acceleration of the ball is going to be determined by the geometry - angle of flipper and pitch of table - and gravity. There's a classic physics problem of rolling without slipping on an inclined plane - you set the angular rotation to be equal to the linear acceleration divided by radius - gives a = (5/7) g sin(theta) for a solid sphere (that first constant will change depending on the moment of inertia of the roller). Or think of this - if you're driving in a car at constant speed and you go over a region with reduced friction (say a wet surface) but not so reduced that the wheels slip, your speed still stays the same, right?
