In a tennis serve, the server should aim to hit the ball over the net in the designated area, but try and optimise their chances of their opponent not being able to return the shot. This can be achieved most effectively with topspin on the ball. ‘When a tennis ball is hit with topspin, the ball drops more rapidly than it would without spin, and the ball tends to rebound low and fast, often making it more difficult for the opponent to return the shot’ (Hall, p.504).
Magnus Effect
A Magnus effect is ‘lift forces generated by spinning balls’ (McGinnis,
p.207). Blazevich states that it is ‘changing of trajectory of an object
towards the direction of spin; from results of the Magnus effect’ (p.240).
