Ball Flight Flaws?

By: B. J. Hathaway, G.S.E.B, M.C.I.


No doubt most of us have read or been taught the Ball Flight Laws. These are the seemingly scientific explanations for the 9 possible variations of travel that a golf ball can make through the air. You've all heard it before when you hit a ball that started left of target and been told that shot was a "pull" and therefore a swing path problem.

The conundrum for those of us who teach and study the physics and geometry of golf is that those ball flight "laws" don't agree with the 30 plus years of study that Homer Kelley put into every aspect of the golf swing which he detailed in his book, The Golfing Machine. For many years TGM has offered an explanation for ball flight behavior based on science. The problem was, nobody wanted to listen because they thought the book was too complicated and its readers "bizarre", and because certain organizations said "these are the ball flight laws and because this is what we say, that's the end of it."

Luckily, now we can find evidence that backs up science, and times - well they are a changing. According to TrackMan data, initial ball direction is determined by two factors, club path and face angle.

"According to the "old" ball flight laws, the initial direction of the ball is 100% dictated by the club path, All the scientific people in the golf industry know that this is very wrong"

Fredrick Tuxen, inventor of TrackMan

According to TrackMan's data, which uses the most advanced technology available, the initial direction of a golf ball is 85% caused by face angle and only 15% by path. This just solidifies what TGM has been saying for years, the ball generally leaves at a 90 degree angle to the face!

Now there are other factors that affect ball flight, such as near-center contact and gear effect which influences side spin, but for most of us the important information is this:

1. Learn to control the club face: phase I of directional control. You must also learn to control the shaft and the club head, but for now let's remember that the lead hand controls the club face. How we control the club face is done by hinge action, which dictates how much the face rotates through the impact zone. Last, but never least, the lead hand must always be flat at impact, no scooping or flipping the wrists!

Any TGM or Medicus Certified instructor can help you understand how to control these three swing elements because when you do, you will control the ball.... and then you will control your game!
