(Phys.org) —From ping pong tables to golf courses, the sizes of sports fields vary widely. Although the sizes of sports fields were originally defined empirically—that is, by simply playing the sport rather than performing calculations—researchers in a new study have found that sports field sizes follow some universal laws. Specifically, the size of a sport field is strongly correlated with the associated ball’s maximum range, which in turn can be calculated from the ball’s physical properties. Furthermore, this correlation allows many sports to be classified into two main categories: “precision and reflex” and “target” sports, reflecting two different styles of human activity.
