yes a one stroke penalty
You have made the distinction between, in the hazard and outside of the hazard, because of course, you can not ground your club in a hazard. If you address the ball but step away and take a practice swing there is no problem. You only incur a penalty if you knock the ball with the club and it moves. Also, a stroke is only deemed to have taken place if you make a genuine attempt to hit the ball.
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.
playing a ball with a club from the teeing ground into the hole by a storke?
No, no penalty. Just watch out. It is a one shot penalty if you hit the bag or equipment with your ball.
No its not because it shouldn't be there
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.
Yes, this is allowed under no penalty. Even if you knock the ball off the tee accidentally with your club there is no penalty, it can simply be replaced on the tee.
Take a 2 stroke penalty
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.
No, the only time you are allowed to ground your club in the bunker is when you are playing an actual shot. If you ground your club in the bunker prior to a stroke it is a two shot penalty.
I am almost positive its when the club strikes the ground and pulls up grass and dirt and that kind of stuff.
