why golf ball have dimples

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 dimples on a golf ball?

Why does golf ball have more mass then a tennis ball?

A golf ball has more mass than a tennis ball because. Contains more matter. Which is a physical change. Evaporation. What is true for all chemical reactions. Total mass of reactants equals the total mass of the products.

How do dimples in golf balls affect their flight?

  • Lift. Lift is obviously the motion which occurs when an object moves upwards, and dimples in your golf ball help to produce this by creating more pressure at the top ...
  • Pressure Drag. As a concept, drag is relatively straightforward. …
  • Skin Friction. …
  • More lift + less drag = more distance. …

Why do golf balls have those little dents in them?

Those dimples serve an aerodynamic purpose. The reason why golf balls have dimples is a natural selection story. Originally, the golf balls were smooth; but the golfers noticed that the older balls, which had been beaten with nicks, bumps, and slices in the cover, seemed to fly further.

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. "Dimples are what make the golf ball fly," said Nardacci.

Do golf balls always have dimples?

Like many inventions, the golf ball dimple was discovered accidentally. By 1930, the dimpled golf ball had become the standard in golfing. A golf ball with dimples can travel almost twice as far as a smooth golf ball.

What are the dimples in a golf ball called?

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.

Who invented golf ball dimples?

Coburn Haskell introduced the one-piece rubber cored golf ball encased in a gutta percha sphere. Then in 1905 William Taylor applied the dimple pattern to a Haskell golf ball, thus giving rise to the modern golf ball as we know it today.

Who invented golf?

Charles Blair MacDonald, who attended St. Andrews University and learned the game at the St. Andrews Golf Links, is considered the father of American golf course architects. In 1893, MacDonald built the Chicago Golf Club, which was the country's first 18-hole course.

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 dimples reduce drag?

First, dimples allow air to flow more smoothly around a ball's surface, which decreases the wake and low-pressure area behind the ball, resulting in less drag. Second, the dimples increase lift by causing the air to move faster at the top of the ball, creating lower pressure there.

What makes a golf ball Illegal?

Legal golf balls can't be smaller than 1.68 inches in diameter. The Polara balls have a diameter of 1.68 inches (the same size as normal). If you have a smaller ball, you'll have less drag and that should give you more distance.

Why do golf balls have 336 dimples?

“A golf ball has dimples to reduce wind resistance or aerodynamic drag, Quintavalla said in a USGA profile on golf ball dimples. “When you reduce it, you can make golf balls go a lot farther.”

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.

How many dimples are on a British 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).

How many dimples does an average golf ball have?

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. Not just any number will do.

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.
