What is a golf ball used for?
A golf ball beside a hole A golf ball is a special ball designed to be used in the game of golf. Under the rules of golf, a golf ball has a mass no more than 1.620 oz (45.93 grams), has a diameter not less than 1.680 in (42.67 mm), and performs within specified velocity, distance, and symmetry limits.
What are the properties of a golf ball?
The ball must possess the fundamental properties of a spherically symmetrical ball. This means that it must be spherical and have a symmetrical arrangement of dimples on its surface. The golf ball’s maximum diameter is 1.68 inches (42.67 mm). The ball is about 2.5 times the width of the cup, thanks to the 4.25-inch hole.
What is inside a golf ball?
Since all golf balls are made by pressing together two halves of a cover, there will always be a seam on the golf ball. Some companies, such as Titleist, do a great job hiding this seam with their dimple pattern. Hopefully, we provided some insight into what is inside a golf ball and the basics of their manufacturing process.
Is a golf ball a sphere?
Golf balls are not smooth spheres; they are covered by a series of dimples. This is for aerodynamic reasons. The dimples encourage the air moving over the ball to transition from laminar boundary layer to turbulent flow a little sooner.
Are golf balls perfectly round?
Official golf balls must be symmetrical in shape, weigh a maximum of 1.620 ounces and cannot exceed 1.680 inches in diameter. Modern, more aerodynamic golf balls have 336 dimples, which are designed to reduce turbulence and allow the balls to travel farther, as well as affect the spin and rotation.
Why are golf balls shaped the way they are?
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.

Why do golf balls have 336 dimples?
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.
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.
What are the dots on a golf ball called?
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.
Why do the golf have dimples?
The dimples in golf balls create turbulence (that means mixed airflow!) which, if done right, reduces drag, making it go farther. The mixed airflow is of two types: laminar and turbulent.
Why are most golf balls white?
In the 17th century leather golf balls were painted white with readily available chalk or lead pigment to ensure they could be spotted amongst the green grass. So why could they soon fall out of favour? White has proven to be an excellent all-round colour for a range of golfing conditions.
What ball has 336 dimples?
American golf ballsOn 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.
Are golf balls directional?
Set the ball up so that the logo or the writing on the ball (some golf balls even have lines or arrows drawn on them) points towards target 2 – the direction you want the ball to initially travel in. Moving the ball in this way is only possible on the tee or if the course is playing with preferred lies.
How many indents does a golf ball?
The number of dimples on a regulation golf ball can vary, but the common number of indentations is 300 to 500 per ball, according to Golf.com.
How do you know if a golf ball is round?
Step three Draw a dot on the ball with a felt tip pen. Step four Hold the ball under the water, spin it, let it go and study the area of the ball that rises to the top. Step five Repeat several times. If different areas rise to the surface each time it is perfectly round.
Are golf balls symmetrical?
Most modern golf balls have about 300–500 dimples, though there have been balls with more than 1000 dimples. The record holder was a ball with 1,070 dimples—414 larger ones (in four different sizes) and 656 pinhead-sized ones. Officially sanctioned balls are designed to be as symmetrical as possible.

Why are dimples important in golf?
Dimples are a necessary part of the design of a golf ball as they greatly affect the amount of lift and drag on golf ball’s trajectory. Over the years, dimples continue to change and evolve. The shape, depth, and number of dimples will vary between golf balls.
What is the best swing speed for a mid compression golf ball?
If you swing between 86mph and to 105mph, this places your swing speed within the mean. A mid compression ball should be ideal for you.
What happens if you have more dimples on a ball?
Generally speaking, the more dimples on a ball, the higher it will fly in the air. This may sound like a good thing, but it does come at a cost.
How many golf balls can you put in a hole?
As the width of a hole is 4.25” wide and a golf ball is only 1.68”, this means you can 2 golf balls inside a golf hole. Today’s professional courses are all designed using the same sized holes. Designers use a tool called a hole cutter to cut out soil from the ground.

When was golf invented?
Golf dates to the period between 960 to 1279 in China during the Song Dynasty era, but in today's game, it's been traced to 1457 in Scotland when players used feather-stuffed balls and club-shaped tree branches to play golf at that time.
What is a birdie in golf?
Birdie is a golf term that originated in the United States and means a score of a 1-under par score on any single golf hole by a golfer. Meaning getting a birdie is a very good score, and the only score better is an Ace (Hole-in-One).
What are the layers of the golf ball?
The five layers consist of the core, innermost mantle, mid mantle, outermost mantle, and the cover. The low compression, softcore promotes low spins and high launches. The innermost mantle has a soft feel and gives low spins using long irons to provide great distances and high flights.
What is a solid core golf ball?
These models have a thin covering made of two layers and contain a larger core. The solid core contains high energy resin or acrylate, which is further concealed using a cut-proof and tough blended cover. It gives this ball more distance by decreasing the slice and hook of the tee. Next, it has a covering made using either Surlyn or a similar material.
What is mid spin golf?
The mid-spinning models lie in between the lower spins and the high spin options and bridge the gap between them. This makes it suitable for golfers who have average swing speed and control.
What causes a golf ball to compress?
Compression occurs when your golf ball squishies after it comes into contact with the clubface as you swing. In this manner, the club helps in propelling the ball forward by compressing the ball during the impact, thereby interacting with the core. You will find that two factors come into action during compression. These are the core of the ball and the swing speed. The higher swing speeds cause more significant impact when you hit the ball, thereby causing higher compression. As a result, the ball's core acts as the engine drives it to a longer distance.
What is the compression rating of a golf ball?
On average, most of the golf balls' compression rating lies between 50 and 100.
What is high spin golf ball?
High Spin Golf Balls: High spinning balls are mainly designed to enhance the ball's spin-off in the air. When you hit a golf ball, it’s released into the air with a sufficient degree of backspin. This ball can further increase this backspin, thereby creating a longer carrying distance.
How many dimples are there on a golf ball?
You will find around 300 - 500 dimples on the ball. The most common amount of dimples ranges between 336 – 392 with a depth of approximately 0.010 inches. Lots of depression will allow your ball to fly higher. However, note that too many can cause more enormous air pressure on the front area than the back resulting in a slowdown of flight. The typical didn't have a measurement of around 7/1000th of an inch depth. Dimples are available in various shapes, which include hexagons, ovals, teardrops, and circles.
Golf Ball Core
As mentioned above, the core of a golf ball is typically made of rubber. Most golf balls have a two-piece or three-piece design.
Are Golf Balls Hollow?
All golf balls on the market today are solid on the inside and are not hollow. Most are made with two or three pieces of the inner material made of rubber and covered with an elastic material. Wondering if golf balls are hollow is a common question, especially for people just starting their golf journey.
How Are Golf Balls Made?
Golf balls are made by taking a rubber core and pressing it between two halves of a golf ball cover. The dimples are then pressed onto the covers based on the manufacturer’s design. These nearly finished golf balls are then painted and stamped with the manufacturer’s logo and golf ball number.
Overview
A golf ball is a special ball designed to be used in the game of golf.
Under the rules of golf, a golf ball has a mass no more than 1.620 oz (45.9 g), has a diameter not less than 1.680 inches (42.7 mm), and performs within specified velocity, distance, and symmetry limits. Like golf clubs, golf balls are subject to testing and approval by The R&A (formerly part of the Royal and Ancient Golf Club of St Andrews) and the United States Golf Association, and those th…
History
It is commonly believed that hard wooden, round balls were the first balls used for golf between the 14th through the 17th centuries. Though they were no doubt used for other similar contemporary stick and ball games, made from hardwoods such as beech and box trees, there is no definite evidence that they were used in golf in Scotland. It is equally, if not more likely, that leather balls filled with cows' hair were used, imported from the Netherlands from at least 1486 o…
Regulations
The Rules of Golf, jointly governed by the R&A and the USGA, state in Appendix III that the diameter of a "conforming" golf ball cannot be any smaller than 1.680 inches (42.67 mm), and the weight of the ball may not exceed 1.620 ounces (45.93 g). The ball must also have the basic properties of a spherically symmetrical ball, generally meaning that the ball itself must be spherical and must have a symmetrical arrangement of dimples on its surface. While the ball's dimples must be sy…
Aerodynamics
When a golf ball is hit, the impact, which lasts less than a millisecond, determines the ball's velocity, launch angle and spin rate, all of which influence its trajectory and its behavior when it hits the ground.
A ball moving through air experiences two major aerodynamic forces, lift and drag. Dimpled balls fly farther than non-dimpled balls due to the combination of these two effects.
Design
Dimples first became a feature of golf balls when English engineer and manufacturer William Taylor, co-founder of the Taylor-Hobson company, registered a patent for a dimple design in 1905. William Taylor had realized that golf players were trying to make irregularities on their balls, noticing that used balls were going further than new ones. Hence he decided to make systematic tests to determine what surface formation would give the best flight. He then developed a patter…
Behavior
Today, golf balls are manufactured using a variety of different materials, offering a range of playing characteristics to suit the player's abilities and desired flight and landing behaviours.
A key consideration is "compression", typically determined by the hardness of the ball's core layers. A harder "high-compression" ball will fly further because of the more efficient transfer of energy into the ball, but will also transmit more of a shock through the club to the player's hands …
Selection
There are many types of golf balls on the market, and customers often face a difficult decision. Golf balls are divided into two categories: recreational and advanced balls. Recreational balls are oriented toward the ordinary golfer, who generally have low swing speeds (80 miles per hour (130 km/h) or lower) and lose golf balls on the course easily. These balls are made of two layers, with the cover firmer than the core. Their low compression and side spin reduction characteristics su…
Marking and personalization
Golfers need to distinguish their ball from other players' to ensure that they do not play the wrong ball. This is often done by making a mark on the ball using a permanent marker pen such as a Sharpie. A wide number of markings are used; a majority of players either simply write their initial in a particular color, or color in a particular arrangement of the dimples on the ball. Many players make multiple markings so that at least one can be seen without having to lift the ball. Marking t…
