Why do golf balls fly up when they hit the ground?
“Once the ball leaves the clubhead, the only thing acting on the golf ball are aerodynamic forces of gravity. It’s the fact that the air is moving faster over the top, and as a result of moving faster, the pressure is lower. That’s what creates the lift force that’s acting in that upward direction.”
Why do golf balls have nicks and cuts?
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 boundary layer reduces drag, making the golf ball go further. Cite This! HowStuffWorks.com Contributors "Why Do Golf Balls Have Dimples?"
What is the impact between a golf club and a ball?
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. The impact typically lasts only 1/2000 of a second, but it establishes the ball's velocity, launch angle and spin rate.
Why do golf balls have dimples?
Next. The reason why golf balls have dimples is a story of natural selection. 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 farther.
What if a golf ball has no 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.
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.
When did golf balls start having 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.
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.
Which brand of golf ball goes the farthest?
The longest golf ball is the Titleist Velocity. This is a two piece ball that is built completely for distance and low ball spin from the tee. Titleist is known for having some of the best golf ball technology on the market, and the Velocity is no exception.

How long do golf balls last?
You can usually get about 10 years out of an unused golf ball, again, provided that it is stored properly. The best temperature for golf ball storage is around 70-80 degrees Fahrenheit.
What is the liquid inside a golf ball?
Contrary to golf folklore, the liquid cores aren't dangerous. Titleist, for example, has used a salt water and corn syrup blend. Today's core is generally made from synthetic rubber -- which may be mixed with bits of metal, such as tungsten or titanium -- or a plastic-like material such as acrylate.

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.
How many dimples are on a Pro V1 golf ball?
388 dimplesThe 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.
How many dimples are on a golf ball?
Anywhere from 300 to 500.
Why are there dimples on a golf ball?

The average golf ball has between 300 and 500 dimples
Golf balls usually have about 300-500 dimples, mostly circular, with an average depth of about 0.01 inch. Some of the more technologically advanced golf balls have hexagonal dimples which increase the ball's performance.
Golf balls with dimples perform twice as better than a smooth golf ball
Ironically enough, it would seem like a smooth ball would perform better in terms of travelling through the air than one with an irregular surface. But, the dimples allow the golf ball to travel twice the distance a smooth golf ball would.
As you probably guessed, the dimples enhance a golf ball's aerodynamic capabilities
The reason why smooth golf balls perform so badly is because of the large amount of drag they create, which reduces the distance the ball will travel through the air. The dimples help create an irregular surface which reduces the drag and increases lift.
Why Do Golf Balls Have Dimples?
There are anywhere from 300-500 dimples on a golf ball. The first golf ball to have dimples was the Haskell ball, developed by Coburn Haskell, in the early 20th century, which was one of the first smooth golf balls.
How Deep Are Dimples On Golf Balls?
The average depth of a golf ball dimple is 1/100th of an inch but fluctuations of 1/1000th of an inch in depth can greatly affect the characteristics of a golf ball’s flight (i.e. drag and lift).
How Many Dimples Are on an Average Golf Ball?
Most golf balls have between 300-500 dimples per ball. The most dimples ever put on a golf ball are 1,070 dimples.
How Many Dimples Should a Golf Ball Have?
The answer to how many dimples should be on your golf ball depends on what you’re attempting to accomplish with the golf ball. If a golfer struggles to get the ball in the air, a ball with more dimples may help them get more lift and carry on their shots.
Do the Dimples Have to be the Same Shape and Size?
No, each type of ball within a brand is different. The depth of dimples on a golf ball is not regulated but they must however be symmetrical.
Does the Number of Dimples Depend on the Brand?
The answer is yes but it is much more precise than that. The number of dimples on a golf ball is determined by the type of ball each brand produces.
Additional Golf Ball Characteristics that Affect Flight
Besides golf ball dimples, manufacturers research two other aspects of the golf ball, the inner core and the outer cover. In addition to its significance in being the first ball with dimples, the Haskell ball also toyed with how the ball was constructed. (Click here for a brief overview of the evolution of the golf ball.)
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.
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 most popular myth about golf balls?
The most popular myth about golf balls is that the center is either poisonous or explosive. Generations of children have been fascinated by the thought that the inside of a golf ball was filled with a poison gas or potentially explosive material. Fortunately, this is nothing but an urban legend.
Who invented golf balls with compressed air cores?
Fortunately, this is nothing but an urban legend. In 1898, B.F. Goodrich produced golf balls with a compressed air core that had the unfortunate habit of exploding from time to time. This may be the origin of the current myth.
Have golf balls changed?
By Jessica Mousseau. Golf balls have not changed much on the outside over the years. However, what's inside has changed drastically over the course of golf's history and continues to evolve today.
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.
When did golf balls start to have indentations?
After that discovery, golf ball makers began etching raised protrusions into balls. 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.
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.
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.
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 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 long do golf balls last?
Keep balls out of your car or attic, which can get pretty hot during the summer. Store them under normal indoor conditions and they should be good for at least five years, if not longer.
What does compression mean in golf?
A golf ball’s compression only tells how relatively firm or soft it feels. It doesn’t predict distance, flight, or spin, and is just one of many design elements working together to determine a ball’s performance. While feel is important to some players, what counts is how the ball performs on every shot.
