The Anatomy of A Putt


	The Anatomy of a Putt 1. Contact between putter and ball For a 10 foot putt the clubhead approaches the ball at a speed of approximately 3-4 mph (depending on the green speed). Impact will last for a little more than 1/2 of 1 millisecond (0.0005 seconds). The energy transfer from the clubhead to the ball is more efficient with a putter than any other club in the bag and approaches (or exceeds) a COR of 0.9 2. Ball leaves green surface with backspin Because the putter has a loft of approx. 3-4 degrees this will "lift" the ball off the surface of the green. The ball is in flight and leaves the putter face with a small amount of backspin. 3. Ball lands, slides and starts forward spin The ball will remain in flight for approximately 4 inches before making contact with the green. Because the ball has backspin it will slide and tend to start rolling for approximately 10-12 inches. Thereafter it will take on a pure rolling motion....and if aimed correctly with the right speed....should fall in the hole!
