The centripetal force . . . can be a string . . .

Thank you, BerntR. You know a whole lot more physics than I do, and I appreciate your contributions. My efforts here hang on my Georgia Tech education (101/2/3 - 201/2/3 long since forgotten ) plus whatever Homer Kelley and his book taught me as it relates to the Golf Stroke.

Jeff,

Forgive the interrupt, but . . .

Could we please take a moment and revisit this idea -- which, either in this thread or another (can't remember) -- started this whole magnificent interchange . . .

In the Golf Stroke, does the Left Arm and Clubshaft function as the "string" (Centripetal Force) keeping the Sweetspot in orbit around its Left Shoulder Center?

Or does it not?

Thank you.
