What physical forces control the proper distance from the pitcher a curve ball breaks?
When the ball initially leaves the pitcher's hand, the forward momentum of the ball is stronger than the sideward aerodyamic force (created by the spin of the ball). However, as the ball slows down (as it approaches the batter), the sideward aerodynmic force starts to overcome the forward momentum of the ball, thus, the ball curves.
