1. Why is it that when you swing a ball around your head, the string or rope attached to the ball is always tilted down a little? That is, the rope isn't parallel to the floor, it is at a bit of angle at down. 2. The ball will continue to move in a circular path if the total force is (mv^2)/r. But what if the force becomes a little weaker than this (but is still directed toward the center of the circle)? In which direction would the ball travel? There is still a force on it, just a little less than (mv^2)/r.
