The Slice is also called undercut the designation of a flip style in tennis and table tennis in which the ball is played with backspin. In tennis and table tennis blow this variant is used with both backhand and forehand.
When you slice the ball is touched with the bat in a downward motion from the back -up to the front - bottom. The on the ball base, relative to the ball top, slowly passing air ( entrained from the ball airborne particles move opposite to the flight direction, which is why the air is decelerated ) and the swirling effect due to the Magnus effect a positive pressure and thus lift. This leads to a flatter, elongated trajectory over the ball without rotation. Tennis ball which is put at the highest point possible. In tennis backhand slice should be played with by stretched in meeting and playing arm, to be slightly open the club face at right angles to the ground. An upper body rotation should hardly take place. The player should be possible to the side to the ball; the shoulder of the striking arm shows to the network. When chip is the movement, as opposed to the normal slice, ended early after the meeting, as the player is usually in shock execution already in forward motion. Often, the slice can only be played with relatively low speeds because otherwise he would fly over the baseline beyond. Although from flat, but at a greater angle than a ball without Slice - After the impact, the ball bounces - because of the extended flight path and because he is held back by its rotation.
In table tennis, the slice, which means there backspin ball, played by the defensive players often far behind the table and far below table level.
This stroke technique is selectively used in tennis as an attack ball, stop the ball or defensive ball. Often the player gives the ball an extra twist sideways ( sidespin ), which causes the ball bounce off the sides after impact. When attacking this stroke technique is used for accurate placement and gives the player time to advance closer because of the slow ball flight to the network. Also on the defensive is used to slice the gain in time in order to allow a player who has been forced out of the middle of the square again to take a more favorable place position. As Stoppball beaten, giving players with higher performance when the ball stop a particularly strong backspin, so the ball hits sometimes even contrary to the direction of movement.
