OK... I'm with you now... I'll attempt an answer before I leave...

Basically I agree with Bio's mentor (Welch), i.e. the brains in that operation. Wether walking or golfing we create "motion" by shifting our CG thereby creating a temporary imbalance. In the golf swing we "fall" (and catch ourselves). Where I differ with Welch's concept its the notion that that its the shear force reaction at the feet that is what's most important. That concerns motion in the horizontal plane but it neglects the larger motion in the vertical (yes I know horz. and vertical are not the "correct" terms here). Bottomline is all golfers are (falling) in some combination of horz AND vert.

Just a suggestion... If yYou want to improve your golf swing, take the spikes off your shoes and go practice hitting off loose dirt (using a tee) where your feet will slip if you apply too much shear force. It will teach you to "fall" in the vertical plane. IMOP that's key.. that's where the "power" is at.

Take a look at young Mike Austin. http://www.mikeaustingolf.com/video/early_lessons.wmv He's falling around a posted left leg. Centripetal acceleration keeps him rotating about his posted left leg the same way it keeps the moon rotating about earth. He's falling in the vertical (not horizontal) plane. Even still, angular momentum is changing ... its not being conserved.

So the normal force distribution/shifting between the two feet is key. Mike called his the compound pivot or weight shifting pivot. http://www.mikeaustingolf.com/video/at_the_top.wmv


I leave you with this: COAM and Kinetic Chain Momentum transfer is BS. Hand path and learning to fall correctly are key and always Swing easy hit hard.

no nmgolfer im interested in delayed hip action..for e.g move the center of mass to the left earlier while the shoulders/arms/hands are still loading . So they move forward on an angle..bit of a lull..and then boom
