The GOAL of a golfer is to get the club head properly oriented and moving on the optimal path with the highest possible velocity. When the mass of the club head meets the mass of the ball MOMENTUM is transfered from the club head to the ball. Everything else is bullcaca.
Is "Bullcaca" a Physics Term?
It's about time someone said that (but don't use "highest possible velocity" short putts). That's exactly what I was going to say. Except the last paragraph needs a few words about the Clubface motion through the Impact Zone otherwise I'll be talking to the Drink Cart Girl while you're looking for your ball.
