The dimples in golf balls create turbulence (that means mixed airflow!) which, if done right, reduces drag, making it go farther. The mixed airflow is of two types: laminar and turbulent.
What is the purpose of 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.
What if golf balls didn’t have dimples?
It’s easy to assume a ball would go farther if it didn’t have indentations all over the cover, but in actuality, a ball without dimples would be nearly impossible to keep in play. ‘Once the ball leaves the clubhead, the only thing acting on the golf ball are aerodynamic forces of gravity.
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.
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.
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.
Who invented dimples on a golf ball?
In the early 1900s, another inventor found that indentations in golf balls performed far better than raised protrusions. 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.
How many dimples does a Pro V1 have?
Then there’s Titleist Pro V1, one of the best beginner golf balls, with 352 dimples. So it’s unmistakable that dimples differ on golf balls from one brand to another. And not only the number of dimples, but also the shape, size (in a way), and more.
How far can you hit a golf ball without dimples?
According 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.
What are golf balls made of?
These days, a golf ball is typically made of a butadiene rubber center surrounded by one or more rubber mantles and topped off with a tough skin.
What are the divots in golf balls called?
This is called the Magnus effect. The dimples on a golf ball deform the air around the ball quickly causing a turbulent airflow that results in more Magnus lift than a smooth ball would experience.
When did golf balls start having dimples?
Over time, however, they began to notice that scuffed, scratched and dented gutta-perchas covered a greater distance than smooth ones. Like many inventions, the golf ball dimple was discovered accidentally. By 1930, the dimpled golf ball had become the standard in golfing.
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.
