Abstract:
1. A testing apparatus for a game ball, the testing apparatus comprising: a rotating clement with a first end, a second end, and a longitudinal axis that extends through the first end and the second end, the rotating element being rotatable about the longitudinal axis; a mount located proximal the first end of the rotating clement and configured to secure to the game ball, the mount being rotatable with the rotating element about the longitudinal axis; an airfoil extending around the rotating element, the airfoil having a rounded leading edge and a tapered trailing edge; and a sensor that detects forces upon the game ball in a first direction and a second direction, the first direction corresponding with a direction between the leading edge and the trailing edge, and the second direction being orthogonal to both the first direction and the longitudinal axis.
