ICT,

Let's assume for a second that we replace Dr J's wording from Impact to impact separation. After any hinge action has taken place.

Does this convert his theory to match TGM?

If not, how is it still different?

No. A straight shot can only be produced by a Force Linear to the Ball. That's the theory applied by TGM.

This goes to the heart of Jorgensens Glancing Blow Theory. There cannot be a straight shot in Golf. Yet Jorgensen believes in "Pushes" and "Pulls". How do you reconcile those shots. Well, here is what he does. At Impact, the Clubface is open 1 degree and if the Ball was struck from the inside from 1 degree or so, a "Push" would result. He is saying that this geometry creates a force linear to the Ball. Did he fall off his chair?

He's assuming that the Clubface doesn't rotate or that all of the forces propelling the Ball are transferred from the Clubface to the Ball in the nano-second at first contact. Or, he's saying that we all "Steer" through the Ball. Actually he is saying that an "Angular Force" applied to the Golf Ball will result in a straight Ball Flight. Are you kidding me?

Let's see: Jorgensen, MIT, Manhattan Project, Homer Kelley, Blue Collar worker. I think I'm going with the Blue Collar worker on this one. "Give me "Collision Dynamics" for One-Hundred Dollars please".
