How do they put the dimples on a golf ball?
Jun 21, 2021 · Golf ball lift, which results from pressure below the ball pushing the ball upwards, is also due to dimples on the ball surface. When a golf ball spins, it makes a lift caused by pressure below the ball being more significant than the pressure above. The dimples cut down drag to optimize the spin effect and increase the lift.
What is the importance of dimples on a golf ball?
How Do Golf Ball Dimples Work? Drag. This force acts in the opposite direction of an object’s motion. It drags an object back, slowing it down and causing unpredictable flight ... Lift. This force acts perpendicular to the object’s motion, typically upward. Lift happens when a …
Why are golf ball dimples make it go further?
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.
Why do dimples on a golf ball allow it to travel farther?
Jun 27, 2021 · Dimples that are on a golf ball are specifically and intentionally designed to alter the aerodynamic properties of the ball while in the air. Part of this is the distance that the ball travels. 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.
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.
Do dimples on a golf ball reduce 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.
Are golf balls perfectly balanced?

Do dimples affect putting?
However, there is a nasty side effect to the dimples that seems to have escaped the attention of golfers until recently - dimpled golf balls are more difficult to putt. Ideally, a golf ball used for putting should be perfectly smooth and round, for the same reason that billiard balls are perfectly smooth and round.
Do dimples make a car faster?
On a recent episode of the TV show MythBusters, special effects experts Adam Savage and Jamie Hyneman ran tests to see if a dirty car is more fuel efficient than a clean one. It turned out that dirt doesn't make a difference to the mileage (in fact it reduced mileage by ~1.5 mpg).Jul 15, 2012
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 many dimples does an average golf ball have?
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
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.

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 ...
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.
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?
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.
Why do dimples affect the distance the ball can go?
The reason why dimples affect the distance the ball can go is because the dimples on the surface of the ball cause the ball to spin in the air. This backspin motion creates a low-pressure zone behind and underneath the ball while in flight, effectively pushing the ball upwards, which translates to longer air-time.
How many dimples does a 1070 have?
The Dimple 1070 has 414 large dimples and 656 small dimples, making it a non-regulation golf ball. The Mizuno RB 566 is a regulation ball that has 566 micro-dimples, which are more dimples than any other regulation golf ball.
What affects the spin of a golf ball?
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.
How does the number of dimples affect the drag of the golf ball?
This means that if you prefer a golf ball to move a little more slowly through the air to compensate for a specific swing or hit style , then the highest number of dimples you can find will be the way to go.
Why is a lower number of dimples better?
Having a lower number of dimples will result in less drag, and so the ball with move more quickly through the air, being slowed down less by the air around it. If you prefer a fastball, then choosing one with a lower number of dimples is a better option for you.
Why are golf ball dimples important?
Golf ball dimples are designed to make the ball fly longer through the air.
What is the dimple on a golf ball?
This might go to explain how something as small as the dimples on your golf ball can make such a big difference to the flight of every shot that you hit. In a game where the little things are so important, the littlest of them all (the dimple) plays a major role. A golf ball without dimples would not perform anything like what you are used to ...
What is the effect of golf ball dimples?
The effect of golf ball dimples aerodynamics means that golfers are able to hit the ball significantly farther, and in a much more-controlled fashion, than they were able to previous to the creation of the dimpled golf ball.
Is golf a game of inches?
To say golf is a game of inches is probably an understatement – it is a game of fractions of inches. This might go to explain how something as small as the dimples on your golf ball can make such a big difference to the flight of every shot that you hit. In a game where the little things are so important, the littlest of them all (the dimple) ...
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.
When did golf balls get dimples?
In 1905 , an English manufacturer named William Taylor registered a patent for a golf ball dimple design. Before long, all golf balls featured dimples that would be more or less recognizable today. As ball technology advanced, so too did dimple science.
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.
How deep is a golf ball dimple?
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.
Why do golf balls travel unpredictably?
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 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.
How much does a golf ball weigh?
Currently, a golf ball is required to have a mass no more than 1.620 ounces, or 45.93 grams.
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 effect of the spin on a golf ball?
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. Ball spin contributes about one half of a golf ball's lift. The other half is provided by the dimples, which allow for optimization of the lift force.
How does the size of a golf ball affect the amount of drag on the object?
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 .
How long does a golf ball impact last?
The impact typically lasts only 1/2000 of a second, but it establishes the ball's velocity, launch angle and spin rate.
What happens when you rotate your hand in the air stream?
As you rotate your hand in the air stream, you vary the amount and direction of the lift and drag forces acting on your hand. A moving object has a high-pressure area on its front side. Air flows smoothly over the contours of the front side and eventually separates from the object toward the back side.
Is a dimple a shape?
Dimples have traditionally been spherical in shape, but it is possible to optimize the aerodynamic performance of other shapes. The HX golf ball by Callaway, for example, uses hexagons ( see image ). Air exerts a force on any object moving through it.
