For those of us who adhere to long established definitions.... COAM cannot and does not apply to the golf swing. COAM is short for Conservation of angular momentum.... Its what causes a spinning ice-skater to speed up as she pulls in her arms (ie decreases here moment of inertia). By definition the ice skater already has all of the angular momentum she will ever have when she begins to spin.... She adjusts her moment of inertia by pulling in her arms and that translates directly to a higher angular velocity. THAT IS COAM.... GOLF ON THE OTHER HAND.... NO SUCH THING OCCURS.

During the golf swing the golfer is constantly adding energy.... The golf swing is a gestalt or EVENT not a situation where energy (angular or otherwise) is being conserved. We're dealing here with long established well defined Mechanics (which is a branch of physics) terminology.... COAM can ONLY apply to an object subject to a CENTRAL force. A CENTRAL FORCE is one that by DEFINITION cannot add to or reduce rotation (a central force is directed though the center of rotation.. by definition!). A golfer is NEVER an object subjected to central force and therefore COAM can NEVER apply to golfer or club... ever

Data? I don't need no stinkin' data because I understand the subject matter.
