Ball Behaviour

Chapter Two of The Golfing Machine is where things get technical. It’s here Mr Kelley explains the science behind the swing. You’ll already be familiar with some of the concepts explained in chapter two if you’ve worked your way through this website. The flail, hinge motion and levers are explained in depth there.

Here I’ll be explaining ball behaviour - why the ball moves the way it does when struck by the club. In order to better demonstrate this information, I’ll be presenting diagrams of the ball from three perspectives. They are; 1) behind the ball, the area where the clubface hits, 2) above the ball, where the target is north of the picture, and 3) the side of the ball, looking at the the player "face on".
To make this section easier still, I’ll be explaining ball behaviour in eight steps.
