Badminton

Badminton is a racquet sport played by either two opposing players (singles) or two opposing pairs (doubles), who take positions on opposite halves of a rectangular court that is divided by a net. Players score points by striking a shuttlecock with their racquet so that it passes over the net and lands in their opponents' half of the court. A rally ends once the shuttlecock has struck the ground, and the shuttlecock may only be struck once by each side before it passes over the net.

Tennis is a game played between two players (singles) or between two teams of two players (doubles). Players use a stringed racquet to strike a hollow rubber ball covered with felt (most of the time yellow, but can be any color or even two-tone) over a net into the opponent's court.
Along with its millions of players, millions of people world-wide follow tennis as a spectator sport, especially the four Grand Slam tournaments: Australian Open, French Open, Wimbledon, and the U.S. Open. The growth of tennis in Eastern Europe and the Far East has been especially notable in recent years.

The shuttlecock is a feathered projectile whose unique aerodynamic properties cause it to fly differently from the balls used in most racquet sports; in particular, the feathers create much higher drag, causing the shuttlecock to decelerate more rapidly than a ball. Because shuttlecock flight is strongly affected by wind, competitive badminton is always played indoors. Badminton is also played outdoors as a casual recreational activity, often as a garden or beach game.

Volleyball is an Olympic team sport in which two teams of six active players, separated by a high net, each try to score points against one another by grounding a ball on the other team's court under organized rules.[1]
The complete rules of volleyball are extensive, but in general, play proceeds as follows. Points are scored by grounding the ball on the opponents' court, or when the opponent commits a fault. The first team to reach 25 points wins the set and the first team to win three sets wins the match.[2] Teams can contact the ball no more than three times before the ball crosses the net, and consecutive contacts must be made by different players. The ball is usually played with the hands or arms, but players can legally strike or push (short contact) the ball with any part of the body.
Through time, volleyball has developed to involve common techniques of spiking, passing, blocking, and setting, as well as specialised player positions and offensive and defensive structures. Because many plays are made above the top of the net, vertical jumping is an athletic skill emphasised in volleyball. This article focuses on competitive indoor volleyball, which is carefully regulated and played indoors. Numerous variations of volleyball have developed for casual play, as has the Olympic spin-off sport beach volleyball.
