Why Golf Balls Have Dimples

Why do golf balls have dimples? While many people may think that this is an unnecessary feature of a golf ball, it actually serves a very practical purpose. Just, what is it that causes the balls to have these indentations on their surfaces?

Why Golf Balls Have Dimples

 

When you look at a typical golf ball, you will see that it is round. Its surface is not like that of other balls. It does not have the same sort of boundary layer, either. This makes it different from other golf balls. What causes the balls to have dimples on their surfaces?

 

The primary reason why this occurs is because the air pressure that the ball experiences as it travels down the course causes it to have an indentation on its surface. How is this possible? When you look at other golf balls, you will notice that they do not exhibit this phenomenon. This is because the balls do not have the same amount of air pressure that is present on a golf ball. They do, however, share the same kind of boundary layer, which gives them the appearance of having dimples on their surface.

 

The second reason why these balls have these indentations on their surface is because of the turbulent air that is present when the ball goes through the air. The air turbulence that exists at high altitudes causes the ball to vibrate as it makes its way down the course. As the vibration occurs, it also causes the surface of the ball to indent. In the case of golf balls, this process occurs at high altitudes, creating the dimples that you see.

 

One of the most popular theories on the origin of golf balls is that they originated in the deserts of Africa. Many scientists believe that, about ten million years ago, large numbers of dinosaurs died out. Because of the massive number of these dinosaurs, there was a huge rush of mud and sand to build up the first golf balls. The mud that was used eventually became the first golf ball material. Over the millions of years since, various sedimentary layers have accumulated on the surface of the ball, creating the visible lines on the outer layer. As time passed, more minerals and other substances began to be deposited on the top of the ball.

 

The second theory on the origins of golf balls is that they were initially created by golfers to help them achieve better shots. Since the balls were so hard and solid, golfers wanted something to hit the ball with that would not break but would make the ball travel farther. The solution to this problem was to create two types of golf balls, one for use by professionals and another for amateurs. The reason this was done was to encourage golfers to use different types of golf balls, each suited to their particular game.

 

The two-piece golf balls that we are familiar with today are generally made from a combination of synthetic and solid rubber. The inner core is made from a heavy grade of rubber called ethyl vinyl acetate (EVA), which is mixed with graphite. The outer layer is generally made from polyester resin. This outer layer has a rubber coating that is semi-translucent so that the golfer can see the reflection of the ball as it flies past. While this is an ideal design, the fact is that the outer layer is not nearly as durable as the inside core, and the two-piece design is prone to damage from impact.

 

The third theory on why golf balls have dimples is that the manufacturers of the ball want to increase the amount of air pressure that is contained in the outer edge of the disc. The more air contained in the surface of the object, the faster the ball will travel and the higher the air pressure will be inside of the object. The most popular golf balls are constructed with an outer edge design that is optimized for maximum air pressure. However, as the object slows down or starts to roll faster, the amount of air pressure in the inside of the sphere begins to drop, causing the ball to lose some of its distance. Many times the reason the balls lose distance is because the air pressure in the center of the sphere has dropped, but the outer edge is still high and therefore causes the ball to roll more slowly.
