A golf ball is the ball created especially for being used in the game of golf. It has a weight of approximately 46 grams and a diameter of approximately 43 mm.
For those wondering what happens when a golf ball is hit, here are some details: the impact only lasts for a short time, somewhere near 1 millisecond. The impact is then responsible for a number of factors such as the ball's spin rate, it's launch angle and it's velocity.
There factors have a great influence on the ball's trajectory and also its behavior once it hits the ground.
There are to major forces that act upon a flying ball: drag and lift. These 2 forces plus the fact that the ball has dimples will make it fly further on the field.
Dimples were added to the golf ball back in 1908 because of the dimple cover had better effects on ball while in air. Today, a classic golf ball has somewhere between 250 and 450 dimples.
Because the aerodynamics are very important to a golf ball, it is recommended that the balls to be cleaned on a frequent basis.
You can't talk about golf without mentioning one of its most important parts: the golf club. There are 3 main categories of clubs: woods, irons and putters.
Woods are used mainly for tee and long-distance shots. Irons have a high versatility and therefore are used for any type of shots.
Putters are used to send the ball into the cup when you are close enough to it.
Clubs also differ from each other due to an important variation: the loft. The loft is responsible for the ball's ascending trajectory.
Under the golf regulations, a player is allowed to use a set of no more than 14 clubs per golf round. Golfers have different opinions when it comes to choosing their set. A normal set usually consists in 1 driver, 2 woods for fairway shots, 7 irons, 1 putter, 1 sand wedge, 1 pitching wedge and 1 free-choice club.
However, long irons are usually avoided by professional players, who prefer to replace them with either hybrids or woods.
