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 holes in a golf ball called?
The dimple count in a modern golf ball
But generally, golf balls today come with around 300-500 dimples. The most common ones sit around 392.
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.
Why are golf balls covered in dents?
Essentially, golfers would have little hope controlling a smooth golf ball. When dimples are added to a golf ball, it creates a tiny layer of air around the golf ball that significantly cuts down drag. This forces the air to flow over a larger portion of the ball, which results in a much smoother ball flight.
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.

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.
Did golf balls always have dimples?
Dimples were first added onto golf ball surfaces back during the gutta percha phase. Coburn Haskell introduced the one-piece rubber cored golf ball encased in a gutta percha sphere.
Why do golf balls travel further than baseballs?
With much lower gravity and much less air resistance, the golf ball will stay airborne longer and travel father. downward movement under the force of gravity only. What is acceleration? A force of attraction between objects that is due to their masses.
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.
How many indentations are on a golf ball?
Most golf balls have between 300 and 500 dimples, which have an average depth of about 0.010 inch.
What is inside a golf ball?
At its core, a golf ball is made from rubber. It is then covered with either plastic, a thermoplastic resin called Surlyn, or urethane, which is an artificial crystalline compound that's also used in pesticides. Ultimately, the golf ball's design will vary.
How far can a person throw a golf ball?
A golf ball can be thrown, on average, about 60 yards. For people who have a very strong arm and a good throwing technique, it is certainly possible for the ball to travel 100 yards or more.
What launch angle produced the longest drive?
A projectile, in other words, travels the farthest when it is launched at an angle of 45 degrees.
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.
Why is a golf ball heavier than a tennis ball?
A golf ball feels heavier than a table tennis ball because a golf ball is denser, that is, it has more mass in a similar volume.
What is the Reynolds number of a golf ball?
The Reynolds number is around 1e5. Comparison of the turbulent wake behind a dimpled golf ball (top), which originates from a turbulent boundary layer separation, and a smooth ball (bottom), which originates from a laminar boundary layer separation.
What is a gutty golf ball?
The Gutty golf ball was created from the dried sap of the Sapodilla tree. It had a rubber-like feel and was formed into ball shapes by heating it up and shaping it while hot. The arrival of the gutta percha ball or "gutty", as it was called, revolutionized the game of golf and allowed its spread to the masses.
Do golf balls explode?
By the 1920s, golf ball manufacturers had stopped using caustic liquids, but into the 1970s and 1980s golf balls were still at times exploding when dissected and were causing injuries due to the presence of crushed crystalline material present in the liquid cores.
What is a balata ball?
Balata ball
ADVERTISEMENT. Balata ball was first used in the 1900s. The balls with balata covering were first produced by Spalding in the year 1903. It is basically a rubber-like material that is present as a covering in golf balls. Balata is the name of a tree in Central and Southern America and the Caribbean.
What is a turkey in golf?
Its origin is almost certainly American in nature. In ten-pin bowling, a trio of consecutive strikes is called a turkey, while six in a row is known as a wild, or golden, turkey. It wouldn't be the first time golf has borrowed from another sport to expand its lexicon. Click here to return to NCG's Golf Glossary.
What is the rarest shot in golf?
Scoring a condor is the rarest event in golf. This is normally a hole in one at a par five (a two at a par six would also count, but this has never been done). Only five condors have ever been recorded: The most recent was Kevin Pon, who made a 2 on a par 6 at Lake Chabot Golf Course on the 10th December 2020.
Why are golf scores named after birds?
A Bogey means one over par. Birdie: In the 19th century, the term "bird" was the equivalent of "cool" or "excellent" - golf scholars believe this is where the term came from. An Atlantic City, New Jersey, course claims that the term originated there in 1903. The meaning being a score of one under par.
When should you throw away a golf ball?
Now, see if your ball is going to float. Drop it in, and walk away for a minute or two. If the cover is intact, then there should be absolutely no leakage to the internal area of your golf ball. If it starts to sink or you see any air bubbles coming up at all, it's a sign that the cover has a microfracture.
What is the furthest someone can throw?
The farthest throw of a Guinness World Records book is 21.876 m (71 ft 9.25 in), and was achieved by Christopher Watson (Canada) at Notre Dame Collegiate in High River, Alberta, Canada, on 14 April 2018.
