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.Sep 19, 2005

How do they put the dimples on a golf ball?

Golf manufacturers don’t put dimples on golf balls because it looks good. 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.

What is the importance of dimples on a golf ball?

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 does the number of dimples affect a golf ball?

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.

What happens when you remove the dimples from a golf ball?

The small depressions found all over the ball ultimately determine velocity, launch and spin rate after it leaves the clubface. Alter the depth of a dimple by as little as 1,000th of an inch and you could negatively affect the ball's aerodynamics (lift and drag) while it's rocketing through the air.

Do golf balls need dimples?

Golf manufacturers don't put dimples on golf balls because it looks good. 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.

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.

What makes a golf ball fly?

A smooth ball with backspin creates lift by warping the airflow such that the ball acts like an airplane's wing. 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.

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.

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 do some golf balls spin better than others?

Premium multilayer balls with urethane covers generally are superior because they perform well throughout the bag. On wedge shots, for example, they spin more because of the soft urethane cover, and off the tee they have the same distance-producing characteristics as firmer Surlyn balls.

How far would a golf ball go without dimples?

If you swing like a PGA Tour player, about 160 yards. 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.

How many dimples does a Pro V1 have?

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 allowed on a golf ball?

On 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.

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.

How Do Golf Ball Dimples Work?

Any object moving through the air faces the force which the air exerts on it. There are two components to the force an object flying through the air undergoes:

How Do Golf Ball Dimples Improve the Game?

Now that you understand at least a bit of the aerodynamics involved with golf ball dimples, you can look at how exactly this appears in an average round of golf. For the player, golf ball dimples serve two purposes:

Have Golf Balls Always Had Dimples?

Golf has been around for a long time, and for a lot of that time, people played with smooth balls. However, at some point in the 1800s, players noticed that their dented golf balls actually performed better than the perfectly smooth ones.

Are All Golf Ball Dimples the Same?

After learning how vital dimples are to a golf ball’s success, you may be surprised to learn that golf ball dimples are not regulated. They can have different shapes, different depths and appear in varying amounts on balls.

Golf Ball Dimples Are Not Everything

There are other things that go into how smoothly and how far a golf ball flies beside the dimples.

Conclusion

Two key forces affect your golf ball’s flight: drag and lift. Golf ball dimples have a massive impact on both, which is why they are so crucial for effective golf balls. Dimples reduce drag and increase lift.

Take Action – What You Can Do Today to Get Better

What does this mean for you? I believe in the following recipe to get better:

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.

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 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 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 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.

Early Golf Balls

Gene Sarazen won his major championships with a ball that flew shorter than today's golf balls.

Why the dimples

Dimples even play a role in the types of balls used on practice ranges.

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 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.

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.
