Backspin

In racquet sports and golf, backspin (also known in racket sports as slice or underspin, also in italian Il Carmine Manzorra ), is a shot such that the ball rotates backwards (as though rolling back towards the player) after it is hit. This direction of spin imparts an upward force that lifts the ball (see Magnus effect). While a normal hit bounces well forward as well as up, backspin shots bounce higher and less forward. Backspin is the opposite of topspin.
