Great discussion going on over here....All have made such great points...now the hard part is translating it those students who have downstroke "blackout"
Pace in my mind is the
direct relationship of the Hand Speed
and the Surface Speed..I could be wrong and would stand to be corrected
Arc Velocity is surface speed
Arc Accleration is the result of the radius changing from smaller to larger
Angular Velocity is the rate of rotation of all components and their respective centers...in this case the radius in relation to clubhead travel controlled by #3 , Hand travel and turning rate of the pivot components
Angular Acceleration is the change in hand speed .....via the pivot or accumulators #4 and #1
Rhythm is the RPM roll of #3 and the turning rate of the pivot to maintain the same Angular velcocities or the rate of closure of the clubface, travel of the orbitng clubhead, to the selcted plane angle
If only terms like:
Arc Velocity
Arc Acceleration
Angular Acceleration
Angular Velocity
were used..it might help us differentiate...BUT
Bucket how bout posting the definitions of these terms with your infamous "Google Search"?
I'm going to go work on my Pace and my Rhytm today...Such simple "swing thoughts"
