 * Spin to Win :  The Physics  of a  Tennis Swing **



In this scenario, the idea of projectile motion applies to the path of the tennis ball when it is hit. The ball's path can be affected by a number of variables, the first (and easily most important) being the angle of the racket face. If the racket face is too open (facing up), the ball will follow a higher and typically farther path. Likewise, if the racket's face is closed (angled towards the ground), the ball will follow a shorter, lower path, and probably one straight into the net. The amount of topspin put on the ball also affects the path of the ball; more topspin will being the ball back to the ground faster.
 * Projectile Motion**

Circular motion plays an important role in tennis. The swing itself uses a backswing, which involves moving the racket back in a circular motion to gain momentum and more power. Circular motion could also relate to the topspin applied to the ball when it is hit. The ball spins when it is in the air so that it comes back to the ground faster (so that more powerful shots can be hit).
 * Circular Motion**

Momentum is crucial in tennis, especially when it ends up as a factor in a match between two advanced players. When the ball is hit, it gains momentum and will continually gain or lose momentum based on each shot. Players can either add or reduce the momentum based different parts of their swing, especially the backswing. The backswing generates momentum through constant movement, and allows for said momentum to transfer to the ball.
