Backspin is a technique used in sports like tennis and golf to create a backward rotation on the ball. When a player strikes the ball with a specific angle and speed, it causes the ball to spin in the opposite direction of its flight. This spin can help control the ball's trajectory and make it bounce higher or change direction after landing. In basketball, backspin is applied when shooting the ball to improve accuracy and control. The backward rotation helps stabilize the ball's flight, making it more likely to go through the hoop. Players often use backspin to enhance their shooting technique and increase their chances of scoring.
