Topspin

spinning motion imparted to a ball (Tennis)

For the video game, see Top Spin (video game).For the amusement park ride developed by HUSS Maschinenfabrik, see Top Spin (ride). In sports, in particular racquet sports, topspin is a property of a shot where the ball rotates as if rolling in the same direction as it is moving. Topspin on a shot imparts a downward force that causes the ball to drop, due to its interaction with the air (see Magnus effect). It can be generated by hitting the ball with an up-and-forward swing, with the racquet facing below the direction it is moving. A topspin shot is the opposite of the slice; topspin itself is the opposite of backspin.
