The ball was illegally released. The ball must be released by the server with one hand (exceptions are made for one-handed players, who may use the racket to release the ball). A miss. It is a fault if the server swings but misses the ball. A hit out is called if the opponent hits the ball away once the player has served it.
There is no penalty for a second violation by the same player during the game. However, the referee has the right to stop the play if he believes that an unfair advantage has been given by a repeated breach of this rule.
A third violation by the same player results in a point being awarded to the opposing team. This means that if your partner commits three violations of this rule you will receive three free points.
The fourth violation by the same player results in a game loss for that player.
Illegal service includes: throwing or swinging at the ball with both hands; hitting the ball with any part of the body other than the racket; touching the surface of the court with the racket except as allowed by rules regarding service returns.
A server who serves illegally loses his serve and cannot continue playing until he properly serves the ball. If the server does not serve properly, then his opponent can choose to take his place on the court without penalty.
Volleyball Serve Regulations Underhand servers must release the ball into the air before striking it; it is forbidden to strike the ball without first releasing it from the holding hand. (Because many leagues do not call this off, players frequently hit the ball without releasing it.)
The server should stand at least 1.5 meters away from the net. If she is closer than this, she will be called for violation of the server's zone rule. While in this position, the server has until the last moment before hitting the ball to decide where it will go; if she hits the ball too high, it will not count and play will continue. If the ball is hit too low, it will not reach the court and the point will end in a loss for the server.
There are two ways to hit the ball: with an open palm or with closed fist. It is recommended that you learn how to do both; then you can make your own decision which method feels most natural to you. Open-palm serving is very popular among beginners because it looks easy. However, experts believe that closed-fist serving allows for more control of the ball and gives the server a better opportunity to choose how high to hit it.
When you are standing behind the service line, face the net. Kick the ball so that it bounces flat toward the middle of the court.
Some players (especially at amateur level) don't throw the ball high enough. They just throw the ball directly to the blade. This makes the unfair advantages for the server: faster ball and spinner serve. You should complain to the referee or refuse to continue to play if the opponent does this illegal serve.
However, as long as your touch with the ball occurred on your own, it is permissible for your follow through to end on your opponent's side. Also, if a ball lands on your side initially and then bounces back to your opponent's side owing to spin, wind, or other factors, you can reach across to strike the ball (but you must not make contact with the net or you will lose the point).
Errors in ball handling Illegal contact with the ball (double touching, lifting, carrying, throwing, etc.) Touching the net with any part of your body while the ball is in play is not permitted. If none of your opponents has utilized three contacts AND they have a player available to make a play on the ball, you can touch it yourself.
4.3 The server has five seconds to serve legally. As long as no swinging action is used to attempt the serve, the server may toss and catch a faulty toss. If the server uses any sort of swing in attempting the serve, they have violated section 2 of the Rules of Tennis and should receive a free point.
During a volley or a serve, a ball may be played off the net. Any portion of a player's body may make contact with the ball. Catching, holding, or throwing the ball is prohibited. A player cannot block or attack a serve from the 10-foot line or inside it.
However, if a player uses their hand to strike the ball after it has touched the net, then this is known as a throw and not a bounce. The server will usually call for a free ball if someone wants to hit a throw.
There are cases where a throw might be called for even if the ball hits the net before touching the ground. For example, if a player is being attacked by an opponent who has jumped over the net, then it would be legal for that player to throw the ball back at him. In addition, if a player is blocking a shot and the ball goes over their head into the stands, then a free ball can be awarded by the referee. However, these situations are rare and should never be used as an excuse to throw balls at opponents.
In conclusion, players can use their hands to strike a ball after it has bounced on the court, but only in order to make a throw. This rule exists because players often touch the ball prior to it reaching the floor which would be impossible if they could also hit it with their hands.
