No. You can have one foot on the ground or no feet on the ground as long as the player has secured the ball. ie. A player can signal for a timeout in mid-air as long as he/she has secured the ball and signaled for the timeout before stepping out of bounds.
There really is no rule on this. The only time you can really touch a player is when they are backing you down in the post (in which you can put one hand or arm on them) or when they have their pivot foot on the ground. Other than that, most touching of other players is considered a foul.
yes
the ball is turned over to the other team
a player can hold it for 5 seconds and dribble it for 10 seconds then he has to make a basketball play
Normally, the center would. But in the case of a jump ball, the player that was fighting for possession of the ball will jump.( what he said)
Double team is when two defensive players are guarding one offensive player. That offensive player is usually the player in possession of the ball.
An offensive player touch the ball when it is in the cylinder. If a defensive player touches it then, it is goaltending and two or three points are awarded.
Whenever a basketball player is dribbling down the court and a defensive player is coming from behind, your teammates/fans yell "wolf" to tell the person with possession of the ball to beware that the defense is about to steal the ball.
The ball is placed where the ball actually is (assuming the player still has "possession") when the player is down by contact or when the knee hits the ground.
An isolation in basketball is where one player (frequently the point guard or shooting guard) is matched up one on one vs. one player on the opposing team; and the teammates of the player with possession of the ball move out of the way so that the ball handler can make is move and try to score a point.
The only 'offensive' player would be the server, who always starts out the point. No player really plays offense or defense, because no player (or pair of players in doubles) always retains possession of the ball. In basketball, football, and soccer, a team or player has possession of the ball, and the opposing team has to prevent the team from scoring. In tennis, the server starts out the point and has the starting offensive advantage, but since tennis players rally (unlike those of basketball, football, and soccer), there is no definitive offensive player.
no
