Friction
Friction affects Tennis in multiple ways. Friction is the resistance that a surface or object comes across when moving over another. The amount of Friction may differ with every type of situation. If there is a lot of friction on a Tennis court, the tennis ball slows down and creates a higher bounce. If there is less friction, then the tennis ball will move quicker and create a slower bounce. There are three different types of friction; Fluid, Rolling, and Sliding Friction. Fluid friction affects Tennis when the tennis ball is in the air. Rolling Friction affects Tennis, when the tennis ball rolls on the ground. And Sliding Friction affects Tennis, when the Tennis ball hits the Tennis racket and slide during a topspin. When a tennis ball bounces and travels toward the opponent after being hit, it has a natural topspin caused by the friction of the tennis court. The friction between the tennis racket’s strings and the tennis ball (As shown in Figure 3) causes the ball to spin forward towards the player when the tennis racket is slid under the ball. These are just several examples of how Friction affects Tennis.
