Basketball is a team sport in which two teams of 5 players try to score points against one another by throwing or "shooting" a ball through the top of a basketball hoop under organized rules. A regulation basketball hoop is comprised of a rim 18 inches in diameter (45.72 cm) and 10 feet high (3.048 m) as well as a backboard. 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. A team can score 2 points from inside the half circle and a 3 point from outside the back circle, a 3 point being harder, therefore gaining more points. 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. It is a violation to walk with the ball or carry it. Disruptive physical contact (foul) is penalized, and free throws will be issued if an offensive player is fouled while shooting the ball. (violations). Also a technical foul is issued when an infraction occurs during a regular game. The most common technical foul is unsportsmanlike conduct with either the players on the team or the coach. This will give the opposing team an opportunity to shoot 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. Basketball is also a popular spectator sport in countries around the world.
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.
