Does the type of golf ball make a difference?
Yes the type of Golf ball does make a significant difference to the quality of your game. Investing in a high quality ball 3-piece golf ball can help a golfer generate more spin, accuracy and distance. Urethane Vs Ionomer Balls The best golf balls are made with a polymer cover called urethane.
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.
What is a three piece golf ball?
Three piece balls are the entry level ball which creates more spin for the golfer. The added layer will allow for noticeable spin separation. I would say this ball is only necessary after you have been playing golf for at least 12 months.
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.
Why is a golf ball shaped like that?

A tiny pocket of turbulence or air disturbance isMoreAs the air travels over one of the dimples. A tiny pocket of turbulence or air disturbance is created on the surface. It tries to go in and then has a region where it's actually detached.
Is a golf ball a perfect sphere?
In almost every other ball-sport, the balls used are perfectly spherical. However, golf balls have weird circular dents in them. There is very simple physics behind the reason golf balls are made this way. Back in the 1850s, golf balls were called gutties.
What is the structure of 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.
What did the original golf ball look like?
In 1618 the 'Featherie' golf ball was introduced, which was made similar to the hairy golf balls but with goose or chicken feathers. Since the featherie golf ball was filled with feathers it was able to be stuffed more full than the hairy, making it harder thus able to fly farther.
What are golf ball dimples called?
What Are Dimples On 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.
Why are golf balls not 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 is golf ball 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.
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.
Is a golf ball hollow or solid?
Golf balls are not hollow, as they are made up of several different materials and pieces. The golf ball is solid throughout, and this is partly what helps players get the distance, ball flight, and direction they need.
Did golf balls always have dimples?
Before long, all golf balls featured dimples that would be more or less recognizable today. As ball technology advanced, so too did dimple science. In the modern era, dimple patterns are thoroughly tested using high-tech equipment to find the optimal design for distance and control.
How many dimples does a golf ball have?
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.
Why does 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.
Who invented the dimples on a golf ball?
In the early 1900s, another inventor found that indentations in golf balls performed far better than raised protrusions. In 1905, an English manufacturer named William Taylor registered a patent for a golf ball dimple design. Before long, all golf balls featured dimples that would be more or less recognizable today.
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.

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).
How big is a golf ball?
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. Additional rules direct players and manufacturers to other technical documents published by the R&A and USGA with additional restrictions, such as radius and depth of dimples, maximum launch speed from test apparatus (generally defining the coefficient of restitution) and maximum total distance when launched from the test equipment.
What is a golf ball?
A golf ball is a special ball designed to be used in the game of golf .
How do dimples work in golf?
Lastly, the pattern of dimples plays a role. By regulation, the arrangement of the dimples on the ball must be as symmetrical as possible. However, the dimples don't all have to be the same size, nor be in a uniform distribution. This allows designers to arrange the dimple patterns in such a way that the resistance to spinning is lower along certain axes of rotation and higher along others. This causes the ball to "settle" into one of these low-resistance axes that (golfers hope) is close to parallel with the ground and perpendicular to the direction of travel, thereby eliminating "sidespin" induced by a slight mishit, which will cause the ball to curve off its intended flight path. A badly mishit ball will still curve, as the ball will settle into a spin axis that is not parallel with the ground which, much like an aircraft's wings, will cause the shot to bank either to the left or to the right.
What is a high spin golf ball?
Another consideration is "spin", affected by compression and by the cover material - a "high-spin" ball allows more of the ball's surface to contact the clubface at impact, allowing the grooves of the clubface to "grip" the ball and induce more backspin at launch. Backspin creates lift that can increase carry distance, and also provides "bite" which allows a ball to arrest its forward motion at the initial point of impact, bouncing straight up or even backwards, allowing for precision placement of the ball on the green with an approach shot. However, high-spin cover materials, typically being softer, are less durable which shortens the useful life of the ball, and backspin is not desirable on most long-distance shots, such as with the driver, as it causes the shot to "balloon" and then to bite on the fairway, when additional rolling distance is usually desired.
Why does a golf ball backspin?
Backspin is imparted in almost every shot due to the golf club's loft (i.e., angle between the clubface and a vertical plane). A backspinning ball experiences an upward lift force which makes it fly higher and longer than a ball without spin.
What causes a golf ball to travel further?
The turbulent boundary layer is able to remain attached to the surface of the ball much longer than a laminar boundary with less eddies and so creates a narrower low-pressure wake and hence less pressure drag. The reduction in pressure drag causes the ball to travel further.
What is the difference between a softer ball and a harder ball?
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 (a "hard feel"). A softer "low-compression" ball will do just the opposite. Golfers typically prefer a softer feel, especially in the "short game", as the softer ball typically also has greater backspin with lofted irons. But drive distance is also of critical importance to many players wanting to get on the green in fewer strokes for a chance at a birdie or eagle, which a softer ball will reduce by wasting some of the impact energy in its compression.
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.
What are golf balls made of?
One piece golf balls do not have a core or a cover. Instead, they’re made from a single solid material called Surlyn. As this is the cheapest golf ball to produce, they’re usually found on mini golf courses and driving ranges.
What does 2 piece golf ball mean?
So what does a 2 or 3 piece golf ball mean? The number of pieces refers to the amount of layers surrounding the core material of the ball. These layers can add speed and grip to your game.
How many layers are there in golf balls?
The number of layers in a ball can affect overall durability and ball trajectory. You’ll often find amateur players using 1 or 2 piece balls, where professional players are instead using 3 and 4 piece golf balls. Generally there are 4 categories of layered balls to choose from.
What is the best material for golf balls?
The best golf balls are made with a polymer cover called urethane. Urethane helps the grooves on your club grip the golf ball more effectively. As Urethanes durability performs well under intense heat, this material is the preferred choice for high quality golf ball design.
How long do you have to play golf to get a 2 piece golf ball?
I would say this ball is only necessary after you have been playing golf for at least 12 months. If you are a beginner I would stick with the 2 piece.
What is the difference between a 2 piece and a 3 piece golf ball?
The difference between a 2-piece and 3-piece golf ball is distance and level of softness. A 2-piece ball is firm and only used on mini golf and driving ranges. A 3 piece golf ball is higher quality and its softer feel offers the golfer better control.
What is the middle cover on a golf ball?
When you look inside a 4-piece ball, you’ll find an extra layer that is not normally found on a golf ball. This added later is known as the middle cover, and it helps create added distance when you are driving from the tee.
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…

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…
