The Rough Surface Technology on Golf Clubs Golfweek

The amount of spin you place on a golf ball directly affects the success or failure of a variety of shots. For example, you must impart just the right amount of side spin on the ball to hit a controlled fade or draw. When you’re hitting an approach shot, you typically want as much backspin as possible on the ball -- particularly if you’re hitting from the rough -- so the ball

But if you roll a wooden ball across that same floor, even though stone is still meeting wood, the ball meanders along as friction takes a vacation. That’s because rolling friction ( a misnomer ) is far weaker than run-of-the-mill sliding friction, because the surface of contact between the ball and the floor is relatively insignificant.
