Flight Laws
Remember the old Ball Flight Laws, by Gary Wiren? One of them had to do with the Path and Face. It goes something like this...THE INITIAL DIRECTION THE BALL TAKES OFF IN IS A RESULT OF THE PATH, AND THE EVENTUAL CURVE OF THE BALL IS A RESULT OF THE CLUBFACE AT IMPACT.
How true do you think this is? If the face is open or closed enough... will the face over-ride the path? The book says in 3-F-7-A... to "Depend on Clubface alignment for direction control." What do you think? |
Hi Lagster, I f believe that the ball flys where the club face is pointing , but if you change the plane line ie direction lets say a open open plane and stance line, this would then produce a clockwise spin on the ball which would produce a slice with the clubface open. the british Pga used to teach that path controlled the ball direction then the clubface, but they changed that to the clubface.

This way and that way.

"If the face is open or closed enough... will the face over-ride the path?"(or "will the path over-ride the face") Does a ball ever touch the ground when hit by a wedge followed by a deep divot? |
Over-Ride

How many of you have ever seen a player that was way under the plane... but every now and then hit a shot that goes straight left(pull)? |

FACE FACE FACE . . . to play golf you have to have a face that has the proper relation to the path of the club . . . that IS the line of compression. |
RESULTANT FORCE!........is Physics

The initial direction the ball takes off depends more on clubface orientation than path; The Search for the Perfect Swing, Cochran & Dobbs, Chapter 20 (1968 ). The amount of curve in the air is the direct result of the size of the angle between the swing path and face aim; ibid. |
Dr Z Strikes again
Dr. Zick answered this one too. Hint: it involved a "D" plane of flight based on the path and face. Face was definately the most important factor in ball flight direction. It was quite a "Z"ummit.:eyes:
