The Golf Ball Secret

The Golf Ball secret exposed! I chose this title for this page because I was so surprised to find out why Golf balls have all those dimples and how do these effect the flight. 

The reason for golf ball dimples should be no more a mystery for you if you have read the explanaintion regarding the baseball and tennis ball structures.

The first golf balls were made from wood and than they were replaced with balls made from goose feathers stuffed into a cowhide cover. In 1848 the golf balls were made from a natural rubber and today there are made from o synthetic molded plastic or from a solid polymer with a durable cover. Some golf balls has a small core a wound rubber yarn or polyurethane body covered with a durable protective layer.

The dimpled ball was used for the first time in 1900s after the golfer noticed that a rougher ball could fly further than a smooth ball. The dimples trap the boundary air layer around the ball with the same effects as in the baseball and tennis ball cases.

Due to the wide spread of this sport around the world there is a huge interest among the manufacturers to come with the best possible golf ball. They have tried dimples of many shapes, sizes and depths. It was found that there is no big difference between 300 and 500 dimples per ball and that the depth of these dimples will affect the drag.
