Why do golf balls have dimples?
Next. The reason why golf balls have dimples is a story of natural selection. Originally, golf balls were smooth; but golfers noticed that older balls that were beat up with nicks, bumps and slices in the cover seemed to fly farther.
Why are golf balls made this way?
There is very simple physics behind the reason golf balls are made this way. Back in the 1850s, golf balls were called gutties. Invented by Dr. Robert Adams Paterson, these balls were made by heating the sap from the Malaysian Sapodilla tree.
What would happen if a golf ball was smooth?
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. This turbulence would cause a tremendous amount of drag on the ball and force it down from the sky sooner.
Why do golf balls fly up when they hit the ground?
“Once the ball leaves the clubhead, the only thing acting on the golf ball are aerodynamic forces of gravity. It’s the fact that the air is moving faster over the top, and as a result of moving faster, the pressure is lower. That’s what creates the lift force that’s acting in that upward direction.”
Why do golf balls have 336 dimples?
Essentially, golfers would have little hope controlling a smooth golf ball. When dimples are added to a golf ball, it creates a tiny layer of air around the golf ball that significantly cuts down drag. This forces the air to flow over a larger portion of the ball, which results in a much smoother ball flight.
What are the little dents in a golf ball called?
Golf balls can have dimples that are deep, shallow, large or small. Some golf balls have different sizes of dimples on the same ball. Dimples come in all different shapes, including circles, ovals, teardrops and even hexagons like a soccer ball.

Why is a golf hole 4.25 inches?
Four-and-a-quarter inches in diameter. R&A ADOPTS 4.25-INCH HOLE SIZE That first hole-cutting implement utilized a cutting tool that was, you guessed it, 4.25 inches in diameter. The folks running the R&A apparently liked that size and so adopted it in their rules for 1891.
Who invented golf ball dimples?
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.
Why do they yell fore in golf?
It Is Derived from the Word 'Forecaddie' Forecaddies were in charge of watching the golf balls and indicating where the golf balls landed. To let the forecaddie know when the ball was being struck, the golfers would yell out forecaddie. Eventually, the caddie part was dropped, leaving just the fore.
Why is a golf ball white?
It was a bright color and was a good alternative compared to the natural brown of the feathery balls. It is not as if high-intensity yellows and neons were available options, so for hundreds of years, white was the standard color.
What if a golf ball has no dimples?
According to Frank Thomas, Golf Digest's chief technical advisor and former technical director of the USGA, a smooth golf ball with no dimples would travel about 130 yards when hit with a modern driver by a tour-caliber player.
Why do dimples reduce drag?
When a ball is rough (has etchings or dimples) the airflow along the boundary of the ball is turbulent, causing a buffer of turbulent air between the ball and the smooth air causing the drag. This turbulent layer clings to the surface of the dimpled ball and allows the smooth flowing air to wrap around the ball better, hence significantly decreasing the size of the wake. Hence, dimples manage to reduce drag by half as compared to a smooth ball.
How do dimples affect lift?
The lower region is of higher pressure compared to the upper, which leads to an upward force. The dimples, increase this imbalance, increasing the lift force.
What is a dimple in golf?
The dimples on a golf ball are simply a formal, symmetrical way of creating the same turbulence in the boundary layer that nicks and cuts do. What is the history of golf?
What is the effect of nicks and cuts on the ball?
At some point, an aerodynamicist must have looked at this problem and realized that the nicks and cuts were acting as " turbulators " -- they induce turbulence in the layer of air next to the ball (the "boundary layer"). In some situations, a turbulent boundary layer reduces drag, making the golf ball go further.
Why Do Golf Balls Have Dimples?
Golf manufacturers don’t put dimples on golf balls because it looks good. There is real science behind their use. A flat or irregular object moves through the air in an inconsistent, fluctuating manner because of how air flows over it. So golf balls without dimples would travel unpredictably through the air. Essentially, golfers would have little hope controlling a smooth golf ball.
What happens if you don't have dimples on your golf ball?
The one with no dimples at all produced a low-flying knuckeball. “The dimples help to create lift,” Nardacci told Wall. “Once the ball leaves the clubhead, the only thing acting on the golf ball are aerodynamic forces of gravity.
How Do I Know Which Golf Ball Dimple Patters Are Right for Me?
Additionally, the size of golf ball dimples and the dimple pattern on golf balls is specific to each model.
How Big Are Dimples on Golf Balls?
The size of golf ball dimples are most frequently measured by their depth. The average depth of a golf ball dimple is roughly 0.010 inch. The circumference of dimples also varies from model to model. While most dimples are spherical in shape, they don’t have to be. Callaway’s HX ball has hexagon-shaped dimples, for example.
How Much Does a Golf Ball Weigh?
Golf ball weights varied dramatically for much of the game’s history. With older golf ball designs dating back hundreds of years, the most consistent thing about their weights, shapes and sizes was the inconsistency.
How many dimples does a Titleist Pro V1 have?
For example, the 2017/18 model of the popular Titleist Pro V1 has 352 dimples on it, while Titleist’s other flagship ball from the same year, the Pro V1x, has 328 dimples. For one manufacturer, the answer to how many dimples on a golf ball was a whopping 1,070, which happens to be the record for the most dimples on a golf ball.
What happens when a ball spins backwards?
When a ball spins backwards, the air pressure underneath it is greater than above it, so the ball rises in the air. Dimples magnify this effect, contributing as much as 50% to the total lift.
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.
