Conservation of Angular Momentum . . .

[12 piece bucket]

Applied force is applied force. As long as the lag pressure is felt at PP3 throughout the down (out and forward) stroke, then the Hitter is still applying force. However, if one plotted lag pressure vs. time during the down stroke, then one might see variation as different components dominate as the force appliers.

Actually, some of the more advanced swing analysis places measure and plot clubhead acceleration during the golf stroke. It is an eye opening and humble experience. The Titleist Performance Center folks probably do it. Don't forget, acceleration makes the world go round.

Witcha . . . but . . . is the force that the Hitter applies the same as Angular Momentum? Or is he overriding it as a result of trying to thrust in a straight line?

Thanks for bearing with me . . . there were some cousins who "got together" in my lineage.

Force is cause. Applying force results in movement. Angular momentum is effect. Mass moving about a fixed point has angular momentum. Applying force (cause) results in the club acquiring angular momentum (effect).

Closely related family members "getting together" (cause) results in (somewhere along the family tree or evolutionary tree - your pick) Bucket (effect). See you already understood the concept, but just had not applied it to the physics (wasn't this easy)!

Very nice, Steph. That concise explanation helps us all.

Bucket, with Steph's description in mind, think of pushing a playground merry-go-round into its rotating motion. The straight line thrust (force) causes the merry-go-round (the mass rotating about a fixed point) to acquire its rotating motion (and hence its angular momentum).

The straight-line 'push' is against the centripetal force of the merry-go-round's fixed structure, and as a G.O.L.F. analogy, is a Hitting Motion.

Similarly, the identical angular momentum could be created by turning the axis of the merry-go-round, thereby inducing a centrifugal force and its 'pull'. This is analagous to the Swinging Motion.
