By "out" I assume you mean off the table. If you hit the cue ball off the table it is a scratch, and is taken in the kitchen. If you hit a playing ball off the table, it is put in the pocket or in the center of the table depending on the rules you decide before the game (traditionally it is pocketed), and it becomes the other players turn. If you hit the 8 ball off the table, you lose.
ADD: Good answer, but slightly incomplete.
First off, I will assume you don't mean billiards, but pocket billiards, and further assume you mean the traditional game of 8 ball, or "Boston".
If the cueball leaves the table(and remains off the playing surface) it is a foul. Except on the break, the incoming player receives ball in hand. On the break, the cueball must be placed "in the kitchen".
If the cue ball leaves the table, but returns, without hitting anything (chalk, light fixture, wall, player) it is legal. The cueball may travel down the rail, spin back on the table, this is fine.
Any object ball that leaves the table is pocketed, and a foul occurs, unless it is the 8 ball, then loss of game occurs.
Session foul you put the black ball in the middle And its ball at hand.
There is no pentalty nor foul. It automatically goes to the opposing team & they have to in-bound the ball.
If the cue ball goes in it is a foul - the pocketed ball may or may not be removed and spotted depending upon the ball and rules of play. In the game of 8 ball, if the other ball is the 8 ball it is loss of game.
i play basketball and if the person with the ball goes up for the shot and you slap him on the arm it is a shooting foul and you go to line to shoot free throws
A ground ball its fair. A fly ball is foul.
Fair. If the ball hits the bag [base] first then goes foul it is fair
The markings on the field has a foul line. This is by the running paths by 1st and 3rd. Any ball that lands in between the foul line is a fair ball. Any ball that lands out the foul line is a foul. When ball rolls on the infield and goes out the foul territory will be called foul. But when ball lands on the outfield and rolls to foul territory is a live ball
It's still foul cause the ball was hit in foul territory. Whether a ball is fair or foul is based on the position of the ball when it is touched. Since the ball was touched when the ball was in foul territory, it would be a foul ball.
If it goes into foul territory before it passes 1st or 3rd base, it's a foul ball. Just like a grounder or bunt that starts fair and rolls foul. If it goes into foul territory past the base it is a fair, live ball.
if it lands in foul territory then yes
This depends upon the game being played. In English Billiards, there is no black ball. In Pocket Billiards, each game is different - In 7 ball, there is no black ball; In 8 Ball, it goes in the center; In 9 Ball, it may be placed anywhere except the apex; In Straight Pool it can go anyplace except the back to corners.
A ball that lands outside of the white lines or a ground ball that goes foul before reaching 3ed/1st base
