What is the nominal density of a golf ball?
Density. Using the numbers from the rulebook, the nominal density of a golf ball is calculated to be approximately 0.65 ounces per cubic inch.
What is the weight of a golf ball?
Golf ball. 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.
Why are some golf balls made with lower density?
Golf balls with lower densities have been produced over the years to prevent them from sinking in water hazards or in ponds on driving ranges. While these balls are legal for play, they have undesirable performance characteristics.
Why do golf balls have different sizes?
A smaller British ball was used prior to the current standardized size, and because the weight requirement was the same, it had a higher density. Golf balls with lower densities have been produced over the years to prevent them from sinking in water hazards or in ponds on driving ranges.
How many ounces are in a golf ball?
Using the numbers from the rulebook, the nominal density of a golf ball is calculated to be approximately 0.65 ounces per cubic inch.
What determines the amount of spin in a golf ball?
The face of the club relative to the path of the swing: This imparts spin on the ball which causes the ball to deviate once it is in flight. The amount of difference determines the amount of spin and therefore the amount of deviation.
What is straight open golf?
Straight-open, the ball starts straight at the target and deviates right in flight.
What does closed face mean in golf?
Closed - The face might be closed relative to the swing path, that is pointing to the left of the path - which causes the ball to spin further to the left.
How many lateral flights are there in golf?
There are two factors which when taken together determine the lateral flight of a golf ball. Each of these has three possible value, so there are six possible lateral flights.
What is the path of a swing relative to the intended target?
The path of the swing relative to the intended target: This can point right of the target, left of the target, or straight at the target.
Can you use pro preferences to select a ball for your own game?
A word of advice if you plan on using pro preferences as some sort of guide to select a ball for your own game: don’t. Find a ball that suits your own game and play that. Touring pros have swing speeds waaayyy faster than the typical amateur hacker (like me, and probably like you), they hit the sweet spot on
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.
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.
How does impact affect golf ball?
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.

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.
