or baseball or that matter. When a player strikes the ball with a club or a bat what difference does "follow through" make? It appears that as soon as the ball is struck it leaves the instrument that struck it. Would it not make logical sense that if the club or bat stopped immediately, the ball would still go the same distance without follow through.
This has nothing to do with the "follow through" question, but the reason for a slice in golf, or a curve ball in baseball has to do with the rotation of the ball.
If the ball is rotating after you hit it, it will curve.
Imagine the axis of rotatioin is perpendicular to the ground. If the ball is speeding away from you, then the side that is rotating away from you is actually moving faster relative to the air, than the side rotating twords you.
This causes lower pressure on the side that has a higher relative wind speed, causing the ball to curve towards the low pressure.
All this thanks to Bernoulli.
