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 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 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.
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.
Do golf ball dimples 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's the hole in golf called?
the cupHole A circular hole in the ground which is also called “the cup”, 4.25 inches in diameter.
How long do unused golf balls last?
about 10 yearsYou can usually get about 10 years out of an unused golf ball, again, provided that it is stored properly. The best temperature for golf ball storage is around 70-80 degrees Fahrenheit.
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.
What makes a golf ball Illegal?
Legal golf balls can't be smaller than 1.68 inches in diameter. The Polara balls have a diameter of 1.68 inches (the same size as normal). If you have a smaller ball, you'll have less drag and that should give you more distance.
How does a golf ball fly?
A smooth ball with backspin creates lift by warping the airflow such that the ball acts like an airplane's wing. The spinning action makes the air pressure on the bottom of the ball higher than the air pressure on the top; this imbalance creates an upward force on the ball.
How many dimples does a Titleist golf ball have?
New Spherically-tiled Tetrahedral Dimple Designs– featuring a 388 dimple layout for Pro V1, and 348 for Pro V1x – are optimized to each model to maximize distance and flight consistency.
Which is better more or less dimples on a golf ball?
The number of golf ball dimples is less important than the shape and depth of the dimples. The number of dimples can affect drag, so it is important to not have too many dimples. Between 330 and 400 dimples is the optimum number. More dimples mean more focussed control over the ball trajectory.
Are golf balls perfectly balanced?
You might not know this, but all golf balls are not balanced properly on the inside. Many balls have a COG that is imperfect, and ANY imperfection of the COG can cause your ball to go off line. These imperfections can cause not only your putts to go off line but your drives as well.
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 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 ...
When did golf balls start to have bumps?
Golf balls began to be produced with raised bumps on them until the very early 1900s.
Do golf balls perform well?
Although golf ball design and features will vary within the acceptable limits, most golf balls will perform equally well over an extended period of time. That being said, choosing the right golf ball for you can be related to feel, swing speed, and personal preference.
Why do golf balls have dimples?
The first golf balls were actually smooth. But as golfers began to play more and more, they noticed that older balls with bumps, scratches, and gashes actually seemed to travel farther.
What happens if a golf ball has no dimples?
Logically it seems like a small ball would travel farther and faster than those with dimples, but that is scientifically not the case. 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.
How many dimples are on a golf ball?
The typical golf ball has between 300 and 500 dimples on average with an average depth of approximately .010 of an inch. The dimples are usually spherical, but other shapes (like hexagons) have been used in experiments to optimize performance. The lift and drag on a golf ball are extremely sensitive to depth.

From Observation to Mathematical Model
As a child, I occasionally would walk around a nearby golf course with my family on rainy days; the only times when no golfers would dare to play. Our own game was to find lost balls from previous, unfortunate players. The person who found the most balls would win.
The Drag Crisis Observation
Throughout history, the flows around many different shapes have been studied by scientists. For example, vortex streets are generated by the flow around cylinders. Although a sphere does not generate this type of large alternating flow structure, the flow characteristics can also be linked to the Reynolds number.
The Reason for the Drag Crisis
First of all, let’s recall that the drag of an object is caused by two sources:
Modeling the Aerodynamic Forces of Golf Balls
Now we understand why golf balls have dimples in the first place. Let’s remember that the drag is lower and therefore the ball can go further. To find out how much further the ball can go, we first need to compute its trajectory.
Finding the Optimal Launch Angle
The effect of the dimples on a golf ball should now be clear: They make the ball go further. However, in practical terms, this does not say much about how I should hit the ball.
Conclusion
In today’s blog post, we answered a seemingly simple question about golf ball dimples, which has to do with the behavior of the turbulent boundary layer over a sphere at a specific range of Reynolds numbers. This also outlines a classical process in engineering.
