golf ball dimples

Dimples are "craters" in the surface of a golf ball.

Definition: The indentations that cover a golf ball. Dimples are aerodynamic devices and changing the shape and depth of individual dimples (or the overall dimple pattern) has an effect on the flight of the ball. Generally, the depth of the dimples is inversely proportional to the height of the ball trajectory; i.e., deeper dimples result in lower trajectories. Changing the circumference and shape of dimples are other ways that manufacturers can produce different flight characteristics.
