a stroke in racket sports such as tennis or table tennis where the player hits the ball with forward spin
Topspin in tennis and other racquet sports is a type of spin applied to the ball by hitting it with the top of the racquet face. This causes the ball to rotate forward as it travels through the air. The effect of topspin makes the ball dip more quickly, allowing it to stay within the boundaries of the court after bouncing. Topspin is often used to give the ball more control and to make it more difficult for the opponent to return, as the ball tends to bounce higher and faster off the ground.
