Yes, if you think you have hit your ball in play out of bounds you must play a provisional ball from the exact same spot as where you played the previous shot from. However, if you know the ball is out of bounds the next ball you play becomes the ball in play.
A provisional ball can be played when a golfer is uncertain if their original ball is lost outside a water hazard or out of bounds. To properly play a provisional ball, the player must announce their intention to hit one before doing so and must play it from the same spot as the original ball. If the original ball is found in bounds, the provisional ball is abandoned. If the original ball is lost or out of bounds, the provisional ball becomes the ball in play.
in order for a ball in basketball to be considered to be out of bounds the ball MUST touch/hit the ground out bounds ... if the ball does not touch/hit out of bounds the ball is still live a play can go out of bounds to throw/pass the ball back in bounds so long as the player that is going for the ball bounds feet are in the air when he makes contact with the ball ...
No, not in golf
If the ball touches the line, it's considered fair play or in bounds.
If his knee touches inbounds, he is considered tackled in the field of play, regardless if the the ball ends up out of bounds. The clock will continue to run
You hit a provisional when the ball you just hit might be lost outside of a hazard. Usually that means you think you have hit it out of bounds or into some sort of mess where it's unlikely that you will find it. Hitting a provisional means that you are taking stroke and distance IF you don't find your first ball. If you find your first ball anywhere in play (whether or not you like where it is or even if it's unplayable) before you hit your provisional after reaching where the ball is likely to be, then the provisional is cancelled and you continue with your first ball, just as though you never hit the provisional. Once you've reached the point where your ball probably is and hit the provisional again, you're stuck with the provisional and the stroke and distance penalty that you took. This is covered in Rule 27-2, see www.usga.org. There are many interesting decisions related to this one, mostly about what constitutes a "lost" ball.
There may be some local variations to speed play, but generally the penalty is "stroke and distance." This means that you add a penalty stroke to your score and hit the ball again from where the original ball was struck. The player has the option of hitting a provisional ball as well.
Yes, if you step out of bounds and then make a play on the ball, it results in a penalty. In football, a player who is out of bounds cannot participate in the play until they re-establish themselves in bounds. If you interfere with the play while out of bounds, the opposing team may be awarded a penalty for illegal participation.
Yes, in volleyball, if the ball lands on the line, it is considered in bounds and the play continues.
In tennis, if the ball hits the line, it is considered in bounds and the point is still in play.
That is called a kick ball. For example, if Team Blue had the ball and they passed it but Team Red kicked it out of play, then Team Blue would pass the ball to his/her teammate from out of bounds.
In association football, the ball must completely pass over the line: on is in.In American football and rugby football, any contact with the line makes the ball or player out of play: on is out.
