Remember pards . . . Thrust is ACTION, Physics . . . it's more about the Endless Belt and Straight Line Delivery Path . . . which is set at angle which would extend out beyond the plane line.

On the other hand, MOTION is the delivery LINE of the clubhead which the geometric basis is the true geometric Plane Line. The Arc of Approach and Angle of Approach are derived from two points on the plane line.

So Thrust action physics is crossline BUT Motion delivery release motions are ON-LINE.

Any better?

What if we just say that thrust delivery, via the PPs, are all straight line BUT, even so, the club head always follows an arc.

Does that clear it up at all?
