To clarify - to get that clubhead accelerating maximally, you do need to be very good at "Transferring Momentum"- from one joint to another, and eventually to the clubhead. Your point is well taken that we are not transferring Mass but we are transferring momentum (massxvelocity) That's what lagster is referencing.
It is a curious irony that the Swinger's Centrifugal Force is largely the result of the Momentum Transfer of the Turning Body (the Pivot) into the Primary Lever Assembly (the Left Arm and Club). And yet, we who teach The Golfing Machine maintain that the Pivot (Body) is best controlled by the Hands and not the other way around.
I know you've done a lot of work in this area that our members would find fascinating. It would make a great new thread in The Lab, and I, for one, would read every word! Could you kick this subject off for us?
Meanwhile, let's all carry on here. This thread has a 'momentum' all its own!
