yes.
Yes, you may do so, the key distinction that you have made in the question is the ball 'out' of the bunker. If the ball is still in the bunker you would be penalised two shots for grounding a club in a hazard. If the ball is no longer in the bunker you are in you may ground the club, but be aware, there is really no need to.
No, you are not allowed to ground your club in the bunker unless you are taking the actual stroke. If you ground the club in a practice swing or prior to taking the stroke it is a two shot penalty.
It is a strategically placed and shaped hole in the ground which is filled usually with sand. You cannot ground your club in it. G1Golf.com says: It is not really a hole in the ground. It is a sand-filled depression in the ground, which, if your ball does into it, it is difficult to get out of. As the above answer correctly states, a player is not allowed to place their club into the sand, prior to hitting the ball. The technique to get the ball out of a bunker is to imagine that the ball is the yolk of a fried egg, and with the club (called a sand wedge), you try to slice up the entire "fried egg", meaning that you actually hit the sand in front of the ball, and not the ball itself. It is too difficult to describe actually! It is worth mention for golfers planning on playing in Russia, that the word 'bunker' there is extremely rude. It is a crude reference to the female genitalia.
yes, you can ground the club before you tee off the only time you can not ground your club is if you are in a bunker or hazard.
I am not sure I understand the question in regards to the grass. If the first one is marked ground under repair you are entitled to relief, of one club length. The other one must be played as it lies, if this means the ball is in the bunker, you must not ground the club whether there sand or not.
No, you are not allowed to do so, you must not rake the bunker or smooth sand over with your feet, as this is deemed to be improved your stance or testing the ground conditions. You will get a two shot penalty for testing, if you do so.
I assume you mean, when has a player addressed a ball outside of a hazard. A player is deemed to have addressed the ball when they have taken their normal stance and has grounded their club behind the ball. The grounding of the club is the key act, if the club is not grounded, address has not been taken. Once the normal stance has been taken, and the club has been grounded the ball has been addressed. You specified outside a hazard, it is good to point out the difference, because you can not ground your club in a hazard, so it is harder to determine when the ball has been addressed.
playing a ball with a club from the teeing ground into the hole by a storke?
we believe that when in any hazard you are not allowed to groound your club and if you want to play the ball out of a hazard you are not allowed to touch any of the grass that grows in the hazard on your backswing
Grounding the club means actually touching the club to the ground when the ball is in a hazard. The club cannot touch the ground until you make you swing.
Yes, if a bunker is marked GUR you are entitled to a free drop. To do so, you remove your ball from the bunker, and from the nearest point of relief you are allowed one club length, you drop your ball and play. If there is water in the bunker and there is no GUR marked you are allowed a free drop in the bunker, no nearer the hole. If you cannot get relief from the water you can either play it or you can take a penalty drop out of the bunker.
When you 'ground' your club you have caused your golf club to come in contact with the ground or another substance such as water, sand or weeds. Generally speaking the subject of grounding a club centres around hazards where you are not permitted to touch the surface or the weeds that exist within an area marked as a hazard. If a player grounds their club in any of these examples they are penalized two strokes for doing so. If a player grounds their club on the putting surface and the ball moves - by gravity, wind or anything else - there is a penalty for this as well.
