It is called a "let" in tennis when the ball hits the net because "Filet" is the French word for net and the game originated in France.
Let is when the ball goes over the net and lands inside the box but hits the net going over, Let is only on a serve. Net is when the ball hits the net and fails to go get over the net.
The ball is still technically in. According to the rules of volleyball, if it hits the net and goes over, it is still in.
Even of the ball hits the top of the net, if it goes over, it is still in play.
A net ball is on any shot that it goes in the net. A let ball is when you are serving and it hits the net but the ball goes in therefore re-serving.
If it hits the net but does not go over then it is a sideout and the other team gets the ball. If it hits the net but goes over, it is playable and the other team must get it or lose a point.
If the ball hits the net and goes over during a serve, it is called a let and is not counted as a fault. If it doesn't go over it is counted as a fault. In play, if the ball touches the net but goes over it is counted and a point is given to the player who hit it; if a ball hits the net but it doesn't make it over, a point is given to the receiving player.
To determine if a serve hits the net, you can watch for the ball's trajectory as it crosses the net. If the ball touches the net and then goes over into the correct service box, it is considered a let serve and is typically replayed. If it hits the net and does not clear it, it is a fault. Observers often rely on visual cues and sometimes the sound of the ball hitting the net to make this judgment.
If a PLAYER hits the net, then it's called as a net violation and the opposite team gets a point, but if the BALL hit's the net, it's still in play.
