Rules state that a lost ball costs you stroke and distance. In other words you add one to your score and go back to where you played the shot originally. If you hit a poor shot and think you may have lost your ball, most golfers will hit what is called a provisional. This means your provisional shot is in play if you can't find the first one you hit. This saves time and removes the necessity of returning to where you hit your shot originally. If you find your original shot you disregard the provisional ball. One addendum, on public courses in casual play, if no provisional ball was hit, most golfers will drop a ball near the spot they lost their ball, add a stroke and play on. Going back to the original spot and replaying your shot is time consuming and not really practical on a crowded golf course.
