Yes
If you are on the green and you hit another ball which is on the green, you receive a two shot penalty and must play your ball where it lies. The other ball must be replaced, you should have asked the other player to move the ball. If however you are not on the green and hit another ball, there is no penalty, you again play yours as it lies and the other ball must be replaced.
sure why not...
Green
You take a penalty stroke if you did not let te other player mark their ball.
The order of play is determined by proximity to the hole. Whether the ball is on or off the green is irrelevant. The player whose ball is furthest from the hole plays first.
Say player A's ball is sitting on the green, if player B's ball hit's A's ball and A goes in the hole, it must be replaced to the original position. If B's ball goes in, it is classed as holed. This scenario applies on if B hits from off the green. If he is on the green and hits A's ball he receives a two shot penalty.
If player A has a golf ball on the green and player B hits a shot from off the green which hits player A's, there is no penalty, Player A replaces their ball as close as possible to where their ball was prior being hit, and player B plays their ball as it lies. However, if Player A has a ball on the green, and player B plays a shot on the green, if the balls collide player A must replace their ball and player B receives a two shot penalty and plays their ball as it lies.
No, because you are not allowed to drop a ball on the green. So you would have to play it out of the bunker. And even if you could drop it on the green it isn't rally in the spirit of the game.
Your ball is replaced, as near as possible to where it was before it was moved, no penalty. Your opponent unfortunately has to play his ball as it lies, if it's in the water then so be it, he would have to take a penalty drop from the water.
When a player is on the green, they will putt the ball towards or into the hole. A putter is used.
Yes and No. This is covered by Rule 22-2 Ball Interfering with Play of the Rules of Golf. Except when a ball is in motion, if a player considers that another ball might interfere with his play, he may have it lifted. A ball lifted under this Rule must be replaced (see Rule 20-3). The ball must not be cleaned unless it lies on the putting green (see Rule 21). In stroke play, a player required to lift his ball may play first rather than lift the ball.
They mark their ball out of courtesy for other players as if one player on the green hits the ball of another they receive a two shot penalty. It is also so the player can clean his ball and line it up.
