What is the reason behind golf balls being dimpled?
Nov 12, 2019 · Why are golf balls dimpled? 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. Who invented the dimpled golf ball? William Taylor
Why are golf ball dimples make it go further?
Why are Golf Balls Dimpled? The dimples, paradoxically, do increase drag slightly. But they also increase "Magnus lift", that peculiar lifting force experienced by rotating bodies travelling through a medium. Magnus lift is present because a driven golf ball has backspin. The same Magnus effect can cause a ball to hook or slice if it has sideways spin.
Why does golf ball have dimples on its surface?
As the golf ball’s dimples cause the air to flow smoother over the ball, it decreases the air resistance on the ball. This means your ball is not pushed around as much by the force of the air resulting in a much more controlled flight. To get your ball to travel, you also need lift, and golf ball dimples are key in this aspect as well.
Why do golf balls fly further than tennis balls?
The dimples on a golf ball help with both lift and drag. There are some serious scientific definitions and explanations that go into why a dimple helps a golf ball fly correctly. 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 happens when you remove the dimples from a golf ball?
The small depressions found all over the ball ultimately determine velocity, launch and spin rate after it leaves the clubface. Alter the depth of a dimple by as little as 1,000th of an inch and you could negatively affect the ball's aerodynamics (lift and drag) while it's rocketing through the air.Jul 1, 2020
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.
Are more dimples on a golf ball better?
More dimples being on a golf ball are not necessarily better. The number of dimples that are on a golf ball is less important than the dimensions of the dimples themselves. Too many dimples mean more drag, and too few dimples mean an unpredictable flight trajectory.Jun 27, 2021
Do the dimples on a golf ball affect putting?
With no significant associations identified with human participants, dimple error is unlikely to have any implications on putting performance. This is also apparent with side spin where only 20% of variance was accountable for one putter-ball combination.
What is the liquid inside a golf ball?
Contrary to golf folklore, the liquid cores aren't dangerous. Titleist, for example, has used a salt water and corn syrup blend. Today's core is generally made from synthetic rubber -- which may be mixed with bits of metal, such as tungsten or titanium -- or a plastic-like material such as acrylate.
How many dimples does a golf ball have on average?
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.Sep 19, 2005
Why are golf ball dimples different sizes?
The dimples work to break the air around the ball in flight, and have two key characteristics that are measured: Lift and Drag. The ideal dimple design is a combination balancing the lift and drag of the ball. We vary the diameters, shapes, total coverage, edge angles to control these two key variables.
How far would a golf ball go without dimples?
about 130 yardsAccording 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.Oct 12, 2004
How many dimples does a Pro V1 have?
388 dimplesThe new Pro V1 has 388 dimples, and the new Pro V1x has 348 (both in a tetrahedral pattern), marking the first time the dimple counts have changed since 2011. Dimple patterns, however, are far more than simply the number of them.Jan 21, 2021
How many dimples are on a golf ball?
Anywhere from 300 to 500.
Why are there dimples on a golf ball?
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...
What golf ball dimples do?
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.
Have golf balls always had dimples?
No, golf balls were originally smooth.
Is it better to have dimples on a golf ball?
Yes. The nicks and cuts were acting as "turbulators" — they induce turbulence in the layer of air next to the ball. In some situations, a turbulent...
Why Are Golf Balls Dimpled?
At one point, all golf balls were smooth and dimple-free. This is because older golf balls were made out of leather or even tree sap, and therefore each ball was a tiny bit different in shape and design than the next one.
A More Scientific Explanation
A basic scientific explanation for why golf balls with dimples play much better than balls that are smooth should be discussed here. Golf balls are affected by lift and drag, and dimpled golf balls improve the ball’s performance in both of these areas.
Conclusion
Although golf balls haven’t always had dimples, we now know that scientifically, they help the balls go farther and higher with every swing, but most of all, they give the player a much better sense of control over the ball so that a better game is played.
How Do Golf Ball Dimples Work?
Any object moving through the air faces the force which the air exerts on it. There are two components to the force an object flying through the air undergoes:
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 is a dimpled golf ball so fast?
In a dimpled ball, however, the airflow changes drastically. The oncoming air enters and exits the tiny dimples (depressions on the surface), thereby spending slightly more time moving over the surface of the ball before leaving it on the back side. Therefore, a much smaller wake is created behind the ball, which reduces drag, i.e. the backward pull on the ball. That’s why a dimpled ball is able to travel much faster and cover a greater distance than a smooth golf ball.
How big should a golf ball be?
In order to be used in official matches and tournaments, a golf ball must meet certain criteria: it should be 4.27 centimeters (1.68 inches) in diameter and its maximum weight shouldn’t exceed 45.93 grams. It should also have a number of depressions or ‘dimples’ on its surface (there are a few other requirements as well).
What does a bigger wake mean?
A bigger wake means a larger area of low air pressure, which means higher drag. A sort of suction is created in that region, which pulls on the ball and greatly resists its forward motion, hence reducing the ball’s speed.
Does a dimpled golf ball have more lift?
A dimpled golf ball not only accelerates faster than a smooth one, but it can also attain more lift, provided there is significant backspin on the ball. Backspin makes the air move backwards faster on the top of the ball than at the bottom, thanks to the dimples.

What are the two types of airflow?
There are two main types of airflow — laminar and turbulent. La minar movement creates less drag but is vulnerable to "separation" — a phenomenon whereby the air layer that clings to the ball as it moves through the air separates from the ball.
