- As the air hits the dimples on a golf ball, small pockets of turbulence are created. This creates a small layer of air close to the surface of the ball.
- 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.
How do they put 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 …
How many dimples are on a standard golf ball?
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. Click to see full answer Considering this, are more dimples on a golf ball better?
What is the importance of dimples on a golf ball?
Apr 20, 2022 · The reason for the dimples on the surface of the golf ball is aerodynamics, which is essential in golf. Aerodynamics provides the golf ball with a controllable and smooth flight through the air by altering its lift and drag. Small pockets of turbulence appear around the golf ball, creating a small layer of air close to the ball surface once air ...
Is less dimples on a golf ball better or worse?
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 do more dimples on a golf ball mean?
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.Mar 18, 2019
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.
How many dimples are allowed on a golf ball?
Generally, the number is anywhere between 300 and 500 dimples. American golf balls, more often than not, come with 336 dimples. While how many dimples on a British golf ball, they have 330 dimples. As for the highest number of dimples, that would be Ultra 500 Series Golf Balls (500 dimples).
Is it better to have more dimples on a golf ball?
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 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.
Why are there 336 dimples on a golf ball?
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.
What ball has 336 dimples?
American golf ballsOn American golf balls, there are usually 336 dimples, while there are 330 on a British ball. However these numbers can vary widely. Golf balls have anywhere from 300-500 dimples. Golf ball manufacturers will manipulate the number, shape, size, and even edge angles to optimize ball flight and trajectory.
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
Which golf balls have the most dimples?
The Titleist Pro V1 ball consists of 352 dimples. You can therefore see that most of the biggest balls in golf today feature around the 320 to 350 dimple mark.Jan 4, 2021
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 .
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).
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.
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.
Who is Nick Lomas?

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.
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.
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 do golf balls have dimples?
The dimples in golf balls allow air to flow smoothly around the ball’s surface and further to its backside. This allows for a reduction in drag by about half. So to answer what are the dimples on a golf ball for, their main job really is to optimize aerodynamics.
What is the difference between a golf ball and a golf ball with dimples?
Drag. Drag is a force that opposes the ball. The lesser the drag, the less resistance to the ball, and the faster it will travel. Now, a golf ball without dimples has a higher drag than a ball with dimples. The dimples in golf balls allow air to flow smoothly around the ball’s surface and further to its backside.
How deep should a golf ball dimple be?
On average, the depth of golf ball dimples should be around 0.01 inches. Then, there’s the shape which can be a circle, a hexagon, or whatever the manufacturer decides it to be. Thus, the size or circumference of each dimple can also vary.
How far can a golf ball travel without dimples?
However, the distance that a golf ball without dimples can travel is only about half the distance that a golf ball with dimples can. This is because the ball’s flight is highly dependent on aerodynamics. To optimize the aerodynamics of a golf ball, manufacturers play with the materials used and the shape and structure of a golf ball.
How does a golf ball affect its aerodynamics?
These would affect mainly how the ball reacts to gravity after the launch. It is also worth noting that hitting the golf ball determines the ball’s speed, angle, and spin rate.
How many dimples are in a golf ball?
Different manufacturers put a different number of dimples in their golf balls. However, they usually range from 302 to 446 dimples. Some balls can have dimples as few as 200, while a few can have as many as 500. Aside from their quantity, dimples can also be varied by their dimensions.
What happens if you hit a golf ball without dimples?
Basically, if you try to hit a golf ball without dimples, you will be struggling with distance. Also, if the dimples are only on one side, you will not be able to hit the ball straight. This is why we only see golf balls with dimples all over.
