What is a stroke on a golf course?

Answer 1

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.

Answer 2

A stroke in its' simplest terms is an attempt to hit the Golf ball, this includes air shots, if you swing and miss, that is one stroke also.
