I'm pretty sure it is when the ball touches two parts of a player's body in succession, or when a player touches the ball twice in a row.
If they touch it twice, it is a double; if they touch it with the palm of their hand and lift it up, it is a lift
Double touch is illegal unless the player touching the ball blocked it. Blocks don't count as a touch.
The volleyball does not touch your palms when doing a bump, set, pancake, sprawl, or a tomahawk.
no part of your body can touch the volleyball net
it doesn't. you can't let it touch the ground
Double contact in the game of volleyball is when one persons hand is on the ball and then another person touches the ball too. If both people touch the ball at the same time, it is not a double contact.
to hit it over the net with out making the ball touch the ground. you cannot double hit and you have 3 tries to make it over.
