An air shot.
This issue would send your round into meltdown! It doesn't matter if you miss the ball or not, a genuine attempt was made to stroke the ball. So, you count the air shot (1 shot) and then playing the wrong ball (2 shot penalty). Again, it does not matter you didn't hit it.
Points in golf are scored by how many times you hit the ball from to tee until it is in the hole. Each time you hit the ball, you get one stroke. 1 stroke equals 1 point.
'Hit' just describes the contact between the cue tip and the cue ball. 'Stroke' is used to describe the technique used to hit the cue ball, which includes a players biomechanics. It's possible to attempt a stroke without actually hitting the cue ball.
It's a stroke that doesn't produce the desired result. All swings are different, so to me the success of a stroke is determined by the outcome. Did the ball end up reasonably close to where you wanted it to go? Then its a good stroke - regardless of how it looked.
Known as a double hit, there is a one shot penalty, this means one stroke will be counted as two.
no it will not be counted if the player scores a six it will be counted
This came from Brent Kelly of About.com:golf. I hope this answers your question. "If the ball is on the teeing ground and you have not yet made a stroke at the ball, then the ball is not yet in play. And accidentally hitting the ball with a practice swing in that situation does not result in a stroke or a penalty. However, once you've made a stroke at the ball on the teeing ground, the ball is considered in play until you hole out. Then the question of whether a practice swing that makes contact is a stroke or penalty (or both) is covered under Rule 18, "Ball at Rest Moved." And here's the ruling: If you accidentally move a ball in play with a practice swing, it's a one-stroke penalty. You must replace the ball to its original position and play it correctly. Failing to replay the ball from its original position results in a total penalty of two strokes in stroke play or loss of hole in match play."
Yeah, no ball is counted as a batsman faced it.
Ball is not counted
The stroke is the method for sliding the cue to strike the cue ball. A good billiard stroke is very straight and level and continues with a follow through after contact with the cue ball.
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.
