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 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.”.
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.
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.

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.
Why do golf balls fly?
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.
Is it better to have 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.
How many dimples are on a Titleist Pro V1 golf ball?
388 dimpleNew 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. Pro V1 maintains its penetrating trajectory while Pro V1x will fly higher than the prior generation.
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.
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 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.
Difference Of A Smooth Ball And A Dimpled Ball
Dimples ensure two things about the ball. Its lift and the distance it travels. As a result, when a ball is hit, it is exposed in the open air. Allowing the air to have complete turbulence and force on the ball. So that the ball can travel smoothly for longer distances, alter the depth of a dimple, and you can see the difference.
FAQs Regarding Dimples And Golf Balls
There is no specific standard regarding the number of dimples on a golf ball. But still, the answer to how many dimples on a golf ball will be, An average golf ball has 300 to 500 dimples.
Conclusion
A golf ball has dimples not to make it look cute. But for the sake of its better performance. So when this difference was seen between a smooth and dimpled ball, it was made sure to change the ball’s structure entirely.
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.
