Ball Flight "Laws"
Seems to be a lot of confusion regarding how swing path and face orientation contributes to the ball flight. Not to mention all the other contributing factors.

Anyone able to give references to a solid online research article based on experiments (highspeed photography) that clearly shows how it actually works and kills the subject for ever?

The Golfing Machine as well the Maltby 800-page "bible" clearly says that the Ball Flight Laws are junk and I believe they are.

How many of you have seen the guy that is sure he is COMING OVER THE TOP, but when you film him he is ON, or even slightly UNDER PLANE? When he picks up the ball flight(visually) he sees it going left, but the left is from the CLUBFACE, in his case.

i have also wanted to see some results on this topic there has to be some hard data out there using iron byron or something

One day with Iron Byron would shut this question down for good. If it hasn't been done, it is way overdue. They have the technology, why don't they use it?

Good call Metallion - Show us the evidence!

Good call, indeed.

It's been discused several times, and it seems everybody have a theory. But noone has ever presented solid research results.

I'm not sure about the BALL FLIGHT LAWS THEORY either.

If the SHAFT and SWEET SPOT are on PLANE and the(SLIGHTLY OPEN) CLUBFACE contacts the INSIDE QUADRANT of the ball at just the right place in relation to LOW POINT, with HORIZONTAL HINGING and proper RHYTHM... THE BALL SHOULD GO FAIRLY STRAIGHT. CHANGES OR ADJUSTMENTS IN THESE FACTORS CAUSE CURVES.

Once all this is in your COMPUTER... you should be able to produce your shots with a very simple cue.

Starting out
Just to start out stating my corrent ideas about this:

The ball will essentially take off perpendicular to the leading edge of the club and to the loft of the club.

Anyone can prove this to himself while putting and chipping. In this case the initial ball direction will to some 99% be determined by how the face is oriented. Clubhead path is essentially not a factor.

Ok. We can all try that (putting and chipping) and agree. Some of us will be surprised and say: I thought the clubhead path mattered more!

Anyway. We can do the experiment and agree. Some surprised, some not.

But as we go to full swing the discussion starts. I have seen at least two top players saying in their instruction videos that to slice/hook the ball you need to:
1. Aim the face at the target
2. Swing out-to-in/in-to-out to slice/hook.

Since this is a contradiction to what we just agreed on (if we ever did ), we have a discussion.

Now do this in your mind: Fit a clubhead aimed left on a car and tee up a ball on the road. Drive the clubhead at 100 mph to impact.

If the instruction videos above were truthful the ball should take off in the direction the car is driving and then spin to the left.

Do we think so?

Some do. I do not.

I think the ball will take off essentially the direction the clubface is aimed and then turn more left.

The question is how the ball deformation (during impact) and re-formation (at separation - introducing vertical and horizontal spin) make the ball:

a) start out in a different direction than above
b) move the ball during flight

There are other factors involved:

Hinge action
How is the clubface changing orientation through impact, and how does that affect the ball?

"Carry-along-for-an-inch" effect
During impact until separation the ball will essentially be caught on the clubface and deformed. The ball will for a very small amount of time go from being stationary to follow the clubface trajectory. So during the deformation phase and until the ball is deformed enough to spring off the clubface its centre of gravity will travel along the same path as the path of the clubface. This will make the ball:
- Spring off the clubface - which is moving and turning
and
- Oriented in a certain way at separation

This implies that the ball will (for a shot where the ball is carried on the clubface for 1/2 inch or so) get its initial direction as a mix of the clubface direction and the clubhead direction. Most sources discussing on this level will say that the ball will go where the clubface is aimed more than it goes in the direction the clubhead is carrying it.

I'd say the reason for this is that the spring-off (reformation) power off the clubface is dominant to the clubhead direction. Heck, if it wasn't the ball would not leave the clubface.

And so on.

Now tear it apart.

I would LOVE to see some highspeed photography as this one, but from a top view and much longer with different hinge actions, different angles of approach etc etc.
