- As the air hits the dimples on a golf ball, small pockets of turbulence are created. ...
- The air flowing over the ball thus sticks closer to the ball’s surface and flows off the ball further back.
- This creates a smaller wake, which means less drag and a ball that flies farther and smoother.
Why are there dimples on a golf ball?
Jun 24, 2021 · The dimples act as artificial turbulators, creating turbulence next to the ball surface and creating two layers of air going around the ball. The top layer is going faster than the bottom layer, i.e., air clings to the ball’s surface, which creates turbulence. This reduces the drag and helps the ball to travel farther than a smooth one.
How does the shape of a golf ball affect its lift?
Sep 19, 2005 · 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 …
What are dimples and how do they work?
The dimples are extremely important in golf ball design. Once we have the final ball design, we measure the spin rates of the golf balls, then design the dimples to optimize the flight. If you have a higher spinning ball, you would look to make the dimples a little deeper, to help keep the flight down. For lower spinning balls, the dimples are typically a bit shallower to help the ball fly …
How many dimples are on the my tour ball?
Jan 14, 2019 · 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. A dimpled ball thus has about half the drag of a smooth ball. Dimples also affect lift.
Do dimples on a golf ball make it fly farther?
Dimples do make a golf ball fly farther. Without dimples, golf balls do not spin well and have too much drag while in flight to travel a long distance. Golf balls with dimples have been proven to travel at least 160 yards farther than smooth golf balls.Jun 27, 2021
Is it better to have more or less dimples on a golf ball?
If you have a higher spinning ball, you would look to make the dimples a little deeper, to help keep the flight down. For lower spinning balls, the dimples are typically a bit shallower to help the ball fly higher and stay in the air.
Do dimples increase aerodynamics?
First, dimples allow air to flow more smoothly around a ball's surface, which decreases the wake and low-pressure area behind the ball, resulting in less drag. Second, the dimples increase lift by causing the air to move faster at the top of the ball, creating lower pressure there.Jun 1, 2016
Why do dimpled golf balls have less drag?
Dimples on a golf ball decrease the separation point of fluid on the ball. This allows laminar flow to continue longer around the surface of the ball, and thus reduce the drag wake.
Why do golf balls have 336 dimples?
Dimples create the aerodynamic ability to hit golf balls for distance. A ball without dimples would not travel very far. The decision to experiment with dimples on golf balls grew out of the discovery that dented or chipped balls actually flew farther and straighter than smooth ones.
Does a golf ball have 336 dimples?
The dimples are usually the same size as one another, but some golf balls have several different sizes of dimple on the same ball. Any number between 300 and 500 dimples is reasonable, and 336 is a common number.Oct 22, 2007
How many dimples are on the PGA ball?
Most modern golf balls have about 300–500 dimples, though there have been balls with more than 1000 dimples. The record holder was a ball with 1,070 dimples—414 larger ones (in four different sizes) and 656 pinhead-sized ones.
Do all golf balls have the same amount of dimples?
The truth is, there is not a single answer to how many dimples are on a golf ball. That's because the number of dimples varies depending on the model and manufacturer. Most often, the number of dimples per golf ball falls between 300 and 500.Mar 18, 2019
How many dimples are on a Pro V1 golf ball?
352 dimplesThen there's Titleist Pro V1, one of the best beginner golf balls, with 352 dimples. So it's unmistakable that dimples differ on golf balls from one brand to another. And not only the number of dimples, but also the shape, size (in a way), and more.
What affects the flight of a golf ball?
The shape of the golf ball flight is determined by the angle of the clubface, in relation to the swing path the club is taking at the moment the ball is struck. Your swing path is the arc that the club head scribes around you as you swing it.May 28, 2020
Does adding dimples to a car increase its gas mileage?
Yes. Apparently, covering your car in clay and dimpling it like a golf ball will result in a significant increase in gas mileage.Oct 24, 2009
How many dimples are in a golf ball?
Most golf balls have between 300 and 500 dimples, which have an average depth of about 0.010 inch. The lift and drag forces on a golf ball are very sensitive to dimple depth: a depth change of 0.001 inch can produce a radical change to the ball's trajectory and the overall distance it can fly.
What is the difference between drag and lift?
Aerodynamicists break down the force into two components: lift and drag. Drag acts to directly oppose motion, whereas lift acts in a direction perpendicular to motion (it is usually directed upward in the case of a golf ball).
Who is Tom Veilleux?
Tom Veilleux, a senior scientist, and Vince Simonds, director of aerodynamic research at the Top-Flite Golf Company, explain. Engineers and scientists in the golf industry study the impact between a golf club and a golf ball to determine the ball's so-called launch conditions.
How do dimples affect golf ball spin?
The number of dimples on a ball affects the drag of the ball, not necessarily the spin. The spin of the ball is affected by the depth of the dimples. Shallower dimples mean more spin. The way the dimples on a golf ball are shaped and laid out is more important than the actual number of dimples on the ball.
Why do golf balls have dimples?
Dimples do make a golf ball fly farther. Without dimples, golf balls do not spin well and have too much drag while in flight to travel a long distance.
Why are dimples important in golf?
The dimples on a golf ball are crucial. They determine all of the major aerodynamic properties of a golf ball, which ultimately determines how well the ball performs during a game. More dimples on a golf ball do not necessarily make the ball better, but rather the way the balls are laid out and how they are designed.
How many dimples are there in a golf ball?
The optimum range of the number of dimples on a golf ball is from 320 – 450 dimples. Less than 320 dimples and more than 450 dimples make the ball very difficult to control and may lead to an inferior ball when compared to others in the same class.
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 is a dimple on a golf ball?
Like many other great inventions in history, dimples on a golf ball were discovered accidentally. Throughout history, golf balls took on many different designs. At one point, they were even constructed with feathers inside them. As golf grew, people started to realize that a golf ball with cuts and scratches in it would fly further ...

How Do Golf Ball Dimples Improve the Game?
Now that you understand at least a bit of the aerodynamics involved with golf ball dimples, you can look at how exactly this appears in an average round of golf. For the player, golf ball dimples serve two purposes:
Have Golf Balls Always Had Dimples?
Golf has been around for a long time, and for a lot of that time, people played with smooth balls. However, at some point in the 1800s, players noticed that their dented golf balls actually performed better than the perfectly smooth ones.
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.
Golf Ball Dimples Are Not Everything
There are other things that go into how smoothly and how far a golf ball flies beside the dimples.
Conclusion
Two key forces affect your golf ball’s flight: drag and lift. Golf ball dimples have a massive impact on both, which is why they are so crucial for effective golf balls. Dimples reduce drag and increase lift.

Why Do Golf Balls Have Dimples?
Surprisingly, many low handicappers don’t know the answer to these questions, or really have an idea concerning why dimples or so important and even whether or not the lack of dimples can have an impact on their performance. But dimples do matter. Believe it or not, these small indentations can make or break a game.
How Do Dimples Affect the Golf Ball Flight?
The dimples on a ball are placed in a symmetrical manner. If the dimples are not symmetrical the ball will wobble, or the ball’s flight can depend on which part of the ball is sideways or forwards as the ball spins
Launch Conditions
In the golfing industry scientists and engineers have studied the impact between the ball and club in order to determine launch conditions. Typically, the impact lasts only a fraction of a second, however, it establishes the ball’s velocity, spin rate, and launch angle.
The Original Golf Ball Design
In the past, golf balls were completely smooth. However, the golfers noticed that older golf balls that were dented and nicked, those that had slices and bumps in the cover, tended to fly much further.
Final Thoughts
Now that you know why are golf ball dimples important, you may have a whole new appreciation for the rough texture and how they have such a major impact on how much spin your ball has and the type of distance it can go. Over the years, the design of the golf ball has evolved.
