586:, 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 symmetrical, there is no limit to the number of dimples allowed on a golf ball. 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 641: 835:
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.

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.

higher quality, or for new balls, when playing in serious competition. Other grades are typically assigned letters or proprietary terms, and are typically differentiated by the cost and quality of the ball when new and the ability of the firm to restore the ball to "like-new" condition. The "top grade" balls are typically balls that are considered the current state of the art and, after cleaning and surfacing, are indistinguishable externally from a new ball sold by the manufacturer.

company's QC. They are thus a good choice for casual play. However, because the balls have been effectively "disowned" for practical and legal purposes by their manufacturer, they are not considered to be the same as the brand-name balls on the USGA's published Conforming Golf Ball List. Therefore, when playing in a tournament or other event that requires the ball used by the player to appear on this list as a "condition of competition", X-outs of any kind are illegal.

Their low compression and side spin reduction characteristics suit the lower swing speeds of average golfers quite well. Furthermore, they generally have lower prices than the advanced balls, lessening the financial impact of losing a ball to a hazard or out of bounds. 3698: 387: 783:
give the best flight. He then developed a pattern consisting of regularly spaced indentations over the entire surface, and later tools to help produce such balls in series. Other types of patterned covers were in use at about the same time, including one called a "mesh" and another named the "bramble", but the dimple became the dominant design due to "the superiority of the dimpled cover in flight".
660:, as obtained from laboratory experiments. The dark line is for a sphere with a smooth surface, while the lighter line is for the case of a rough surface (e.g. with small dimples). There is a range of fluid velocities where a rough-surfaced golf ball experiences less drag than a smooth ball. The numbers along the line indicate several flow regimes and associated changes in the drag coefficient: 950:. In this format, each ball used at the range has an RFID with its own unique transponder code. When dispensed, the range registers each dispensed ball to the player, who then hits them towards targets in the range. When the player hits a ball into a target, they receive distance and accuracy information calculated by the computer. The use of this technology was first commercialized by 261: 927:. 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 tools such as stamps and stencils are available to speed the marking process. 848:
thus greater physical strength to properly compress at impact. If the compression of a golf ball does not match a golfer's swing speed, either a lack of compression or over-compression will occur, resulting in loss of distance. Other choices consumers must make include brand and color, with colored balls and better brands generally being more expensive.
819:"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. However, a softer ball reduces drive distance, as it wastes more energy in compression. This makes it more difficult for players to get a 531:, causing eye injuries to children who happened to dissect a golf ball out of curiosity. 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. 860:
To accomplish these ends, practice balls are typically harder-cored than even recreational balls, have a firmer, more durable cover to withstand the normal abrasion caused by a club's hitting surface, and are made as cheaply as possible while maintaining a durable, quality product. Practice balls are

The tree is tapped and the soft, viscous fluid released is a rubber-like material similar to gutta-percha, which was found to make an ideal cover for a golf ball. Balatá, however, is relatively soft. If the leading edge

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 do not 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

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

425:. The sap had a rubber-like feel and could be made spherical by heating and shaping it in a mold. Because gutties were cheaper to produce, could be re-formed if they became out-of-round or damaged, and had improved aerodynamic qualities, they soon became the preferred ball for use. 329:, were used for golf from the 14th through the 17th centuries. Though wooden balls were no doubt used for other similar contemporary stick and ball games, there is no definite evidence that they were actually used in golf in Scotland.
