- As the air hits the dimples on a golf ball, small pockets of turbulence are created. ...
- 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 the dimples on a 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.
How many dimples are on a standard 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 …

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.
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

When you reduce it you can make golf balls go a lot farther.
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.
How many dimples are on the average 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.Sep 19, 2005
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
Do golf ball dimples 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.
What are the divots in golf balls called?
The small indentations on a golf ball are called "dimples." This unique design has led to many questions from curious golfers. In this guide, we'll answer these questions related to golf ball dimples and the golf ball in general, including: How many dimples are on a golf ball?Jun 6, 2021
Why is a golf hole 4.25 inches?
The size the R&A mandated? 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.
How many dimples does a Pro V1 golf ball have?
The 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
Do golf balls all have the same amount of dimples?
The truth is, there is not a single answer to how many dimples are on a golf ball. That's because the number of dimples varies depending on the model and manufacturer. Most often, the number of dimples per golf ball falls between 300 and 500.Mar 18, 2019
Which sports ball generally has 336 dimples?
Learn more physics! The dimples are usually the same size as one another, but some golf balls have several different sizes of dimple on the same ball. Any number between 300 and 500 dimples is reasonable, and 336 is a common number.Oct 22, 2007
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...
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.

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 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).
Who is Tom Veilleux?
Tom Veilleux, a senior scientist, and Vince Simonds, director of aerodynamic research at the Top-Flite Golf Company, explain. Engineers and scientists in the golf industry study the impact between a golf club and a golf ball to determine the ball's so-called launch conditions.
Why do golf balls have dimples?
As much as half of the lift a golf ball receives is caused by a backwards spinning motion. 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 many dimples are on a golf ball?
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 big is a golf ball?
But now balls are required to have a consistent size. According to the rules, the diameter of a golf ball must not be less than 1.680 inches, or 42.67 mm.
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?
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.
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 is the force that acts perpendicularly to the ball's trajectory?
Lift is the force that acts perpendicularly to the ball’s trajectory. This is almost always directed upward. A golf ball without dimples would have a lesser lift than a golf ball with dimples.
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.
What are golf balls made of?
Nowadays, the golf balls that can be found in the market are usually made of synthetic resin and urethane skins. These materials allow for better consistency in flight and more durability. All these advancements in golf ball technology allow us to enjoy golf the way we do today.
