Different golf balls can affect the outcome of your shot. The different constructions of each ball can change the possible distances of the ball's flight. While different individuals may achieve different results with each ball, construction has an effect on the outcome. The dimples affect the airflow around the ball and different dimples have different effects. Golf balls didn't always have dimples on them. The balls used when playing golf were made of wood. They then evolved into the bird. A feathered is a leather pouch filled with wet goose feathers. As the skin dried, the ball shrank and hardened. They worked well in good weather, but when the birds got wet they didn't work so well. After the creation of the bird, other types of golf balls were created. The guttie was a rubber ball that worked well in wet conditions, unlike the Featherie. As the guts were used, players found that dirty, battered balls that had chunks coming off worked better than new, smooth balls. Ball makers began making molds with bumps and ridges so the balls would fly better at the start of the game. After the discovery that non-smooth balls fly better, dimples were born in the world of golf. The dimples serve to decrease drag on the golf ball. They delay the separation of air particles from the ball. In doing so, the dimples create less drag allowing the ball to travel a greater distance. Drag occurs faster when air particles separate from the ball at a normal rate. This happens because there is space between the ball and where the particles separate, creating a vacuum effect (Smith, 2010). Every company makes golf balls differently.
