The object of the game is to use a long-handled stick (known as a "crosse" or lacrosse stick) to catch, cradle, and pass a solid rubber lacrosse ball in an effort to score by hurling the ball into an opponent's goal. Cradling is when a player moves their wrists and arms in a semi-circular motion to keep the ball in the pocket of the stick's head using centripetal force. The head of the lacrosse stick has a mesh or leather net strung into it that allows the player to hold the ball. Defensively, the object is to keep the opposing team from scoring and to dispossess them of the ball through the use of stick checking and body positioning. The rules of women's lacrosse are different from the men's lacrosse game. Equipment required to play is also different from the men's. In the United States, women are only required to wear eyewear or lacrosse goggles and a mouth guard. Internationally, women are only required to wear a mouthguard, and have the option to play without protective goggles. The stick has restrictions too, as it must be a certain length and the pocket must be shallow enough to show the ball above the side when held at eye level.
