Golf balls, on the other hand, are 4.267 cm in diameter, or 1.6”. These minimum sizes increased from 1.62” in 1990. While you may have trouble telling which ball is larger simply by looking at them, most people can easily tell which one is heavier when they pick them up.
Do golf balls have different densities?
A Golf Ball has a density of 1.015 g/mL with water having a density of 1 g/ml so a Golf ball will not float as it is heavier. In Saltwater, the density is 1.025 g/ml, it is heavier than a Golf ball so the Golf ball will float. Density is the measure of how much material there is in a set space.
How did you determine the density of your golf ball?
Students can also bring in materials to test whether or not they will sink or float. Additionally, students can calculate the density of the golf ball using the density = mass/volume algorithm. 12.
Does a golf ball sink or float?
We recommend testing them at home with a bucket of water rather than out on the course, just in case. So, do golf balls float? Real golf balls don't float because they are denser than water. Fake golf balls float because they are hollow and less dense than the water.
What is the volume of 1 golf ball?
I calculate the volume of a golf ball to be about 2.5 cubic inches (4/3 * pi * . 85) as . 85 inches is the radius of a golf ball. Divide that 2.5 cubic inches into 1.6 million and you come up with 660,000 golf balls.
How do I calculate density?
The formula for density is the mass of an object divided by its volume. In equation form, that's d = m/v , where d is the density, m is the mass and v is the volume of the object.
How do you find the density of a ball bearing?
Well generally, density is found by dividing the mass of the object by its volume. The mass can be easily found by weighing, and since a ball is a sphere all you'd need is the radius of the ball (or diameter). Well generally, density is found by dividing the mass of the object by its volume.

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.

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…
