How Do Golf Ball Dimples Affect Lift and Drag?
- 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 create a thin boundary layer of the air that adheres to the ball’s surface. This allows the air to stay on the ball’s surface a little …
What is the importance of dimples on a golf ball?
· For the golf ball: The transition from the laminar to turbulent boundary layer occurs for lower Reynolds numbers, due to small vortices induced by the dimples. This generates a smaller wake and therefore a smaller drag. The drag crisis is …
Why are golf ball dimples make it go further?
· Golf Monthly. Dimples on a golf ball are so important because they help create turbulence in the layer of air around the ball which reduces drag and therefore makes the ball fly further. It is widely believed that a golf ball without dimples would fly about half the distance of a golf ball with dimples because of this technology. This is ...
Why do dimples on a golf ball allow it to travel farther?
· A typical golf ball has 300 to 500 dimples, with an average depth of 0.010 inches. Most are spherical, though some companies have adopted a hexagon shape in order to reduce drag further. Golf ...
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.
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.
What are the two main reasons golf balls have dimples?
The Short Answer Adding dimples to golf balls creates a thin layer of air that sticks to the surface, minimizing the drag behind the ball and increasing the lift of the ball—allowing it to go higher and move forward faster.
Why do golf balls have dimples and on average how many dimples are there?
By adding dimples to the ball, golf ball manufacturers minimize drag forces that pull back on the ball or slow it down. Dimples also help lift the ball by forcing airflow downward, which pushes the ball upward. These are the same principles of aerodynamics that airplanes use to fly.
Are golf balls perfectly balanced?

And one of them is to use the a little electric spin balancer that spins the ball up to high RPM you put a mark on it.
Why is a golf ball rough on its surface?
Rough balls fly through the air more easily than smooth ones. As air flows around a smooth ball, it breaks away from the surface, forming a pocket of swirling currents at the back, like the wake behind a speedboat. This wake creates "drag" on the ball, slowing it down.
What are the dimples on a golf ball called?
What Are Dimples On A Golf Ball Called? What is this? In most cases, golf ball dimples are simply referred to as dimples. However, there are some instances when they will be called indentations or more thoroughly referred to as the golf ball dimples pattern.
How many dimples are on the PGA 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).
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 is a golf ball white?
It was a bright color and was a good alternative compared to the natural brown of the feathery balls. It is not as if high-intensity yellows and neons were available options, so for hundreds of years, white was the standard color.
Why do they say fore in golf?
A possible origin of the word is the term "fore-caddie", a caddie waiting down range from the golfer to find where the ball lands. These caddies were often warned about oncoming golf balls by a shout of the term "fore-caddie" which was eventually shortened to just "fore!".
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...
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 ...

Why Do Golf Balls Have Dimples
The typical golf ball has multiple dimples in it that make it distinct for playing golf. And if you’re wondering why golf balls are dimpled, you’ll probably be surprised with the answer.
The Structure of a Golf Ball
Let’s look further into the structure and construction of a golf ball. It will enable you to understand way beyond why do golf balls have dimples.
Why are Golf Ball Dimples Different Sizes
The primary reason why are golf ball dimples different sizes varies from manufacturer to manufacturer. The variation of why are golf ball dimples different sizes also applies to the circumference.
Why are There 336 Dimples on a Golf Ball
Along with the size, why are there 336 dimples on a golf ball is also a frequently asked question by golf enthusiasts?
Function Over Design
And so, the final verdict as to why do golf balls have dimples lies in function over design.
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.
How do dimples affect golf ball spin?
The number of dimples on a ball affects the drag of the ball, not necessarily the spin. 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.
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.
How many dimples are there in a golf ball?
The optimum range of the number of dimples on a golf ball is from 320 – 450 dimples. Less than 320 dimples and more than 450 dimples make the ball very difficult to control and may lead to an inferior ball when compared to others in the same class.
