Hi,
This has been bugging me for a little while now. Imagine a ball is rolling along on a rough surface without slipping. Under ideal conditions it will just continue rolling indefinitely right?
However, if you were to draw a free body diagram the normal and gravitational force would cancel out and you'd have friction. How does friction not cause the velocity of the ball to change when it's the only force acting?
