Golf balls can have dimples that are deep, shallow, large or small. Some golf balls have different sizes of dimples on the same ball. Dimples come in all different shapes, including circles, ovals, teardrops and even hexagons like a soccer ball.
What are the dents on a golf ball called?
The small indentations on a golf ball are called "dimples." This unique design has led to many questions from curious golfers. In this guide, we'll answer these questions related to golf ball dimples and the golf ball in general, including: How many dimples are on a golf ball?
What are the small ridges on a golf ball called?
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.
What are the spots on golf balls called?
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 do we call the round indentation on a golf ball cover?
The surface is covered in little indentations called dimples, and they serve an important purpose! If the surface of the ball were smooth, it would greatly alter the flight of the ball. In the past, older beat up golf balls were being used in place of new unblemished ones.
41 related questions foundDid golf balls always have dimples?
When Did Golf Balls Get Dimples? The invention of golf ball dimples happened accidentally. In the mid-1800s, the most widely-used golf balls were known as gutties, which were first created by Robert Adams Paterson using molded tree sap.
Why do planes not have dimples in golf balls?
About 90% of the drag of a smooth sphere shape is pressure drag and the rest is friction drag. Putting dimples on surface will increase the friction drag but will reduce the pressure drag by having the turbulent boundary layer attached farther before separation.
What do more dimples on a golf ball mean?
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 dimples appear on golf balls?
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.
Do all golf balls have the same number of dimples?
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.
What is the line on a golf ball for?
If a golfer likes to pick a specific point to putt to — a small target six inches right and three feet short, for example — then go ahead and use a line. This allows the golfer to aim perfectly and when they are stroking the putt, they can simply attempt to control distance.
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. You'll also notice that illegal balls are slightly heavier.
What is a feathery golf ball?
The first "real" golf ball was known as a "feathery"golf ball. Basically, the feathery was a leather sack filled with boiled goose feathers, then stitched up and painted. Feathery golf balls were expensive to make easily damaged and only the privileged few could afford to use them.
Can you dent a golf ball?
A single dent is noticeable enough. An incident with a golf ball can leave you with ugly stretched damage that can really take away from the beauty, value, and look. Conventional body shop repairs for golf ball damage tend to be much more expensive and time consuming.
Do golf ball dimples 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.
How many dimples does Titleist TruFeel have?
Because the soft rubber core is larger, the new TruFeel feels softer to many golfers. The 376-dimple, tetahedral-patterned cover has not changed for 2022, but the TruFlex cover itself is thinner. It should help golfers obtain better performance around the greens.
Which golf balls have the most dimples?
The Titleist Pro V1 ball consists of 352 dimples. You can therefore see that most of the biggest balls in golf today feature around the 320 to 350 dimple mark.
How does a vortex generator work?
Vortex generators act like tiny wings and create mini wingtip vortices, which spiral through the boundary layer and free-stream airflow. These vortices mix the high-energy free-stream air into the lower energy boundary layer, allowing the airflow in the boundary layer to withstand the adverse pressure gradient longer.
Why are airplane wings smooth?
A certain amount of air turbulence occurs on the surface of most aircraft wings, regardless of their shape and size. As air moves across a wing, it's altered by the friction between it and the wing's surface, changing from a laminar, or smooth, flow at the forward area to more turbulent flow toward the trailing edge.
Do dimples reduce skin friction?
In effect it's a positive trade-off: "The ball pays a skin friction penalty, but gains a pressure drag advantage," Maughmer says. The difference is huge in terms of the distance a golf ball can be driven, he adds. Dimpled balls can travel nearly twice as far as smooth ones.
What were golf balls made of before plastic?
During the early “featherie era”, the best balls were made by the Dutch and their featheries were extremely popular in Scotland as well. Until the mid-19th century, the featherie was the standard golf ball. It was made of cow or horsehide which was stuffed with feathers; most often goose feather.
Do old golf balls have any value?
Because of the age and the craftsmanship put into these balls they are among the ones that have the highest price tag of collectible golf balls. These balls are referred to as antique, and goes for sums upwards of +$5000! See example from eBay below.
What are feathery balls made of?
The cover of a feathery typically consisted of three pieces of leather stitched into a sphere. The feathers stuffed inside were typically goose feathers, sometimes chicken feathers. First, the feathers were boiled for several hours to soften them.
How much is a feathery golf ball worth?
Feathery golf ball - Price Estimate: $4000 - $6000.
What were Gutties?
From the late nineteenth century, we find examples in both English and Scottish sources of gutta and gutty (or guttie) as a term for a golf ball made with gutta-percha. These golf balls replaced those made with feathers. Guttie has also been used as a term for a catapult.
