Why do dimples on a golf ball allow it to travel farther?
Dimples on a golf ball create a thin turbulent boundary layer of air that clings to the ball's surface. This allows the smoothly flowing air to follow the ball's surface a little farther around the back side of the ball, thereby decreasing the size of the wake.
Why do golf balls have those little dents in them?
Those dimples serve an aerodynamic purpose. The reason why golf balls have dimples is a natural selection story. Originally, the golf balls were smooth; but the golfers noticed that the older balls, which had been beaten with nicks, bumps, and slices in the cover, seemed to fly further.

Why does golf ball have dimples on its surface?
Their design (i.e., size, shape and pattern on the surface of the ball) will help dictate the ball’s trajectory. Discovery of the Dimple. Some 600 years ago, someone observed that an older, used ball with a roughened surface performed better than a new, smooth one – hence the origin of “dimples.”.
Who invented dimples on a golf ball?
Coburn Haskell introduced the one-piece rubber cored golf ball encased in a gutta percha sphere. Then in 1905 William Taylor applied the dimple pattern to a Haskell golf ball, thus giving rise to the modern golf ball as we know it today.
Was the invention of dimples on a golf ball was designed to take advantage of aerodynamic principles?
Dimples that are on a golf ball are specifically and intentionally designed to alter the aerodynamic properties of the ball while in the air. Part of this is the distance that the ball travels. Dimples do make a golf ball fly farther.
How golf ball dimples reduce drag?
Golf ball dimples reduce drag by creating a turbulent boundary layer flow around the ball. The boundary layer is defined as a thin layer of fluid dragged by the ball. By creating this turbulent boundary layer, the separation point decreases.
When were dimples first put in golf balls?
This new breed of golf ball also featured a much larger variety of outer designs for improved airflow. The mesh, reverse mesh and Bramble designs gave way to the dimple pattern first used in 1908.
Why do golf balls have dimples?
A golf ball’s dimples allow for a smooth, controllable flight and also give the ball lift by impacting the way the air flows around the ball. There is science behind the design, and the dimples are not just for show.
Why are dimples important in golf?
Aerodynamics is all about altering the lift and drag on an object, and this is the purpose of the dimples on a golf ball. Aerodynamics is extremely important in the game of golf.
Are All Golf Ball Dimples the Same?
After learning how vital dimples are to a golf ball’s success, you may be surprised to learn that golf ball dimples are not regulated. They can have different shapes, different depths and appear in varying amounts on balls.
How do dimples affect golf ball lift?
A golf ball’s lift comes from its spin. The spinning motion of a golf ball causes the pressure beneath the ball to be greater than the pressure above, which causes lift. The dimples optimize the spinning effect by cutting down drag and increasing the ball’s lift.
How does a golf ball travel?
To get your ball to travel, you also need lift, and golf ball dimples are key in this aspect as well. About half of the lift you get on a golf ball is caused by the spin on the ball, but the other half is due to how well the dimples optimize this spinning.
How deep is a golf ball dimple?
The average depth of a golf ball dimple is 0.010 inches, but this too can vary slightly.
What happens when air flows over a ball?
The air flowing over the ball thus sticks closer to the ball’s surface and flows off the ball further back.
How do dimples work in golf?
As it turns out, the dimples make the game of golf possible. The dimples facilitate aerodynamic optimization, or the ability of the ball to travel longer distances by influencing the lift and drag of an object in the air. (Lift goes in the direction perpendicular to motion; drag opposes motion.) According to Scientific American, a dimpled ball travels twice as far as a smooth one would. That’s because the dimples produce a boundary of air around the ball, reducing the wake of air as well as the drag. They also act as turbulators, inducing turbulence in the layer around the ball.
How many dimples are in a golf ball?
The depth of the dimples can also make a huge difference. A typical golf ball has 300 to 500 dimples, with an average depth of 0.010 inches. Most are spherical, though some companies have adopted a hexagon shape in order to reduce drag further.
Why does a golf ball have dimples?
If a golf ball was completely smooth with no dimples, this backspin would warp the air around it and produce an unpredictable amount of lift. When dimples are added to the ball’s design, however, the air has somewhere to go around the ball. This allows more lift to occur as the force of lift is optimized in relation to the quality of strike from the club.
What is the role of dimples in golf?
Dimples also play a role in the shape of a golf ball’s trajectory. Accuracy is an imperative part of golf, and dimples allow for a repeatable shot shape if struck in a pure, consistent manner. A golf ball’s dimple construction will allow the ball to cut through the air with back and sidespin, create a ball flight shape. A ball without dimples, however, would fly in an unpredictable manner that will be more difficult to repeat.
What affects the ability of a golf ball to fly?
As you might suspect, dimples on a golf ball affect its ability to fly after being struck by a golf club.
Why do golf balls have dimples?
Very simply stated, if a golf ball were smooth, the air would flow quickly over the top and create quite a bit of turbulence behind the ball.
What do the Dimples on a Golf Ball do to Ball Flight?
A great alternative to this question is, what would happen if there were no dimples on the golf ball? This experiment was conducted by Titleist several years back, and the result was a line drive type shot that wavered on its line. The ball only went about half as far as a dimpled ball, and the ball flight was not nearly as high.
Are There Different Dimple Patterns and How Do They Affect Ball Flight?
Most golf ball dimples are spherical. They follow a pattern, and generally, one will be shallow, followed by a deep dimple across the surface of the golf ball. Major manufacturers seem to be more likely to change materials or interior makeup of a golf ball before they alter the dimple pattern.
How Many Dimples Will Work Best for My Game?
If all this talk about golf ball dimples has you thinking that the number of dimples on your ball could be causing your slice, you are probably looking for a solution in the wrong place.
What is a dimple in golf?
Dimples give the golf ball the correct amount of lift and drag to promote the best possible result with each swing. Nick Lomas is the founder of GolfSpan, an avid golfer, not quite a pro but has over 15-years of experience playing and coaching golfers from all over the world.
How many dimples are there on a golf ball?
The average golf ball has about 336 dimples on it. Most have anywhere from 250 to 500. The interesting thing about dimples is that they must be symmetrical, but there is no limit to how many you can have on a ball. There was once a golf ball created with 1700 dimples on it.
When did golf balls start to have bumps?
Golf balls began to be produced with raised bumps on them until the very early 1900s.
What happens if a golf ball has no dimples?
Picture a smooth golf ball sailing through the air. The sun is out . The birds are chirping . There is an ideal amount of wind. As the ball moves, the front will come into contact with the air.
What is the effect of dimples on a ball?
This allows the air to stay on the ball’s surface a little longer as it moves around the back side of the ball. This decreases the ball’s drag. (Drag is the force that takes place as a result of a change in velocity, opposing the motion and slowing it down.)
How does the dimple affect the lift of a golf ball?
The dimples on a golf ball also affect its lift. If the ball was smooth, the ball would get lift from its backspin. This makes the air pressure on the bottom of the ball larger than the air pressure on the top, creating an upward force. The spin contributes to about half of the ball’s lift, while the other half is produced by the dimples which optimize the lift so the ball can go even higher.
What is the area behind the ball that has been disturbed as the ball passes through the air?
Scientists soon learned why this is: it all has to do with something called a turbulent wake region. When a ball is traveling through the air, the air flows over the front side of the ball and towards the back where it will eventually separate as the ball continues to soar. The turbulent wake region is the area behind the ball that has been disturbed as the ball passes through the air. Makes sense, right? Stay with us.
How does air affect golf ball drag?
The air that hits the front of the ball will smoothly go over the ball and separate from the ball at the back. That separation will create a turbulent wake region that results in low pressure, making the ball drag. So much drag, in fact, that a smooth golf ball would only travel half as far as a dimpled golf ball.
