BasketBall

Basketball is a team sport in which two teams of 5 players try to score points against one another by placing a ball through a 10 foot (3.048 m) high hoop (the goal) under organized rules. A regulation NBA basketball court is 94' long by 50' wide. Basketball is one of the most popular and widely viewed sports in the world.

Points are scored by throwing (shooting) the ball through the basket from above. The team with more points at the end of the game wins, but additional time (overtime) may be issued when the scores of both teams are the same. The ball can be advanced on the court by bouncing it (dribbling) or passing it between teammates. Disruptive physical contact (foul) is penalized, and free throws will be issued if an offensive player is fouled while shooting the ball.

Through time, basketball has developed to involve many common techniques of shooting, passing and dribbling, as well as players' positions, and offensive and defensive structures. Typically, the tallest members of a team will play center or one of two forward positions, while shorter players or those who possess the best ball handling skills and speed, play the guard positions. While competitive basketball is carefully regulated, numerous variations of basketball have developed for casual play. In some countries, basketball is also a popular spectator sport.

While competitive basketball is primarily an indoor sport, played on a basketball court, less regulated variations played in the outdoors have become increasingly popular among both inner city and rural groups. Measurements and time limits discussed in this section often vary among tournaments and organizations; international and NBA rules are used in this section.

The object of the game is to outscore one's opponents by throwing the ball through the opponents' basket from above while preventing the opponents from doing so on their own. An attempt to score in this way is called a shot. A successful shot is worth two points, or three points if it is taken from beyond the three-point arc which is 6.25 meters (20 ft 6 in) from the basket in international games and 23 feet 9 inches (7.24 m) in NBA games. A 1 point basket is able to be earned when shooting from the foul line when a foul is made.

Games are played in four quarters of 10 (international) or 12 minutes (NBA). College games use two 20-minute halves, while high school games use 8 minute quarters. Fifteen minutes are allowed for a half-time break, and two minutes are allowed at the other breaks. Overtime periods are five minutes long. Teams exchange baskets for the second half. The time allowed is actual playing time; the clock is stopped while the play is not active. Therefore, games generally take much longer to complete than the allotted game time, typically about two hours.

Five players from each team may be on the court at one time. Substitutions are unlimited but can only be done when play is stopped. Teams also have a coach, who oversees the development and strategies of the team, and other team personnel such as assistant coaches, managers, doctors and trainers.
