Art with all your research have you ever tested the theory that a larger/longer swing arc always contributes to more speed? Always just assumed that the taller you are the more potential you have for speed because you are able to create a longer swing arc to create more speed.
Dear Jim,
First an apology for the delay in responding, my 78 year YOUNG memory could not help in re-locating this post of yours, a growing problem for me as 'traffic' increases in the questions being asked, a problem I am very much enjoying.
Jim, very early, in fact about a month after I started this 5 year 'seeking golf truth journey', I set down a few VERY basic equations to in an almost "back of the envelope" sense, use them to guide me to the MOST important characteristics driving club head velocity. I promise NOT to turn this post into a physics lecture, but let me assure you that your intuition is correct, with one small modification. The longer path MUST be traveled in approximately the same downswing time as the shorter path, and I am not trying to be 'cute' here. Of course, if there was NO acceleration or deceleration of the body parts, a longer path traveled in the same time would BY DEFINITION be going faster.
BUT there is a WHOLE BUNCH of accelerating AND decelerating as seen in the kinematic sequence, so let me get to the next BASIC physics piece that supports your intuition. IF the center of rotation of the swing was constant (we know it is not, but as a first order understanding), the club head speed developed is PROPORTIONAL TO the length of the swing arc, AND the torque applied to the rotating element, the club. So, all the elements affecting club head spped seem to be enhanced with a taller , wider arc individual, BUT CAUTION HERE, as the torque generating AND timing issues can easily over-ride the size advantages.
One quick story, however. Just a few weeks ago, as is my habit, I was just observing some golfers at a local driving range, and was fascinated by a 6 foot 9 inch well coordinated individual hitting right-left-right etc army shots, but always reaching the 250 yard fence on a bounce, in both cornrers. My ACTION CLUE, is when ANY golfer on the range demonstrates DISAPPOINTMENT, or worse yet ANGER from the result vs the expectation difference in the shot. This golfer, later I would learn, had been drafted by the Detroit Pistons out of Giorgia Tech, and was now just a businessman, but clearly IMO, still a very coordinated athlete.
Well as I am sure you have already predicted, I approached him, cautiously, noted my interest in golf science and testing, and predicted in a few minutes he would be having a lot more fun with golf. Skeptical, he let me demonstrate BBKIB, and yes, his first AND EVERY SHOT AFTER THAT cleared the 250 yard , 50 foot high fence, and best of all, down the middle, no more army shots.
An exaggeration, no, that is not my style or desire, just IMO golf truth, breaking thru, in thuis case Jim, with a tall person, I believe coordinated, and capable, because also from the physics, and your intuition, capable of hitting it further.
Hope that answers your question Jim,
Regards,
art
