WHAT'S IN A GOLF BALL?

By Lee MacRae

In the chemistry of air pressure, turbulence, and aerodynamics, surface structures are vital physical element. History has it that there are things that seem to be peculiar on their make-up hundreds of years ago which eventually came up with a better composition based on scientific research. And a golf ball is the best paradigm of this theoretical stand in history.

During the earliest days of golf on the eastern coast of Scotland, most players used ancient apparatus in order to play the game in a more disorganized and informal way. Here, the first clubs and golf balls are made up of wood.

It was on 1618 that the feather golf ball was finally introduced. This was commonly known as the "Featherie". This feather golf ball was a handcrafted ball made with goose feathers securely pressed into a horse or cowhide sphere. This is being done while the ball is still wet. After drying, the leather shrank and the feathers expanded creating a hardened ball.

But because these kinds of golf balls are specially handcrafted, they usually cost higher than the clubs. In doing so, only a few privileged people could afford to play golf during those times.

Next came the Guttie golf ball. This prehistoric kind of golf ball was made from the rubber like sap of the Gutta tree that can be found in the tropics. Normally, these Guttie balls can be easily shaped into a sphere when hot and eventually used as a golf ball. With its rubber nature, guttie balls can be cheaply reproduced and can be easily repaired by reheating and reshaping.

However, between the two earliest forms of golf balls, the feather golf ball was said to travel farther than the gutties. This is due to the smooth surface of the gutties that limits the capacity of the golf ball to cover more distance.

With this new scientific analysis, the developers of golf ball finally came up with balls with the "dimples" that are predominant in modern golf balls nowadays.

Dimples are crafted into golf balls so as to reduce the aerodynamic drag, which will be acting on the ball if it were totally smooth. This is because smooth balls, when sailing through the air, leave a huge pocket of low-pressure air in its stir therefore creating a drag. With the application of drag, the ball slows down.

Hence, by having dimples on golf balls, the pressure differential goes down and the drag force is reduced. These dimples create turbulence in the air surrounding the golf ball. This, in turn, forces the air to clasp the golf ball more closely. By doing so, the air trails the warp created by the ball towards the back instead of flowing past it. This results to a smaller wake and lesser drag.

Dimples also help players to put backspin on a shot making the golf ball break off on the putting green.

The idea of putting dimples on golf balls can be traced back during the gutta percha phase. Coburn Haskell introduced the one-piece rubber cored ball encased in a gutta percha sphere. It was during this time when the players observed how their shots become more and more predictable as their balls turned rough from play.

When William Taylor applied the dimple pattern to a Haskell ball in 1905, golf balls finally took their modern form.

From then on, dimpled golf balls were officially used in every golf tournament. In 1921, the golf balls took its form with standard size and weight.

Today, there is an abundant selection of golf balls to fit different golf game and condition. There are golf balls that offer control, while some offer distance. In whatever ways golf balls vary, only one thing is common and known. Golf balls are not just elements of the sports arena; they are more than ever paradigm of a concept in physics.

On the downswing is where the key is. YOUR HEAD MUST REMAIN BEHIND THE BALL AT IMPACT. If you look at a face-on picture of any good player in the history of the game, they all have their head behind the ball at impact. You can even see in players like Nick Faldo and Greg Norman, that they actually move their head to the right to start the downswing. This just creates a more powerful, underneath, impact position. If you get your head moving laterally left BEFORE you strike the ball, you basically have no chance. You will be way steep, way over the top, and way far from hitting a good shot!

Wood Game Tip
Many people complain about not being able to hit the ball well with their woods (or metals), and in particular their driver. From what I've seen poor quality contact is a major problem for many of these players. Put a tee in the ground (without a ball) sticking up approximately 1 to 1.5 inches. You should be able to strike the tee consistently without hitting, or even brushing, the ground at all. If you miss the tee, or touch the ground in any way, don't wonder any longer why you can't hit your driver. Remember -- the longer the club, the more precision required. Practice this exercise until you can consistently clip the tee without touching the ground (or even the grass). Once you get quality contact handled the feedback you get from your shots becomes meaningful. Then you can work on directional control.

Don't worry that once you set the driver down it doesn't align with the ball. The ball isn't on the ground - it's three inches above the ground!
