There’s a lot of science that goes into the construction of a golf ball. Take the dimples on the ball, for instance. The dimples on a golf ball are there to help the ball get lift into the air and to promote spin. It’s similar to how an airplane’s wings are specially built to allow the plane to get lift and get into the air.
Every golf ball has what is called a compression number. This number refers to how tightly packed the contents of the golf ball are inside the shell. So a golf ball with a high compression number will feel much harder on impact than one with a lower number. Typically the numbers range from 80 to 110.
