It is called a foot fault. You can also have a foot fault if you step over the center line onto the opponent's court.
It is where you would serve from.
You can serve from anywhere on the back line of the court.
behind the end line
yeah it is
one violation in volleyball is hitting the net while volleying with the other team
They have to be behind the serving line, but they can jump past this line when serving.
A foot fault is when in volleyball you serve and you pass the line or put your foot under the net.
a serve is when a player on a team is behind the white line and hits it over the net; make sure you don't foot fault :)
Behind the out-of-bounds line. how far back from the line depends on what type of serve you are doing, if you are doing a jump serve you'll probably stand back a ways, if you are doing an overhand serve it depends on how strong of a server you are or how experience you are.
