Basketball is a team sport played with five players on each side on the court. The standard team features two guards, two forwards, and a center. The five positions are known by unique names and numbers: point guard (PG) or 1, shooting guard (SG) or 2, small forward (SF) or 3, power forward (PF) or 4, and center (C) or 5. Over time, basketball positions have evolved towards a positionless game, where players are free to shoot and dribble based on their skills. The game has also spawned many variations, such as wheelchair basketball, half-court basketball, and donkey basketball.

Basketball court dimensions
The dimensions of a basketball court vary depending on the level and type of basketball being played. In the National Basketball Association (NBA), the court measures 94 feet by 50 feet (28.7 by 15.2 metres). This is slightly larger than the court used in international competitions under the International Basketball Federation (FIBA), which is 28 by 15 metres (91.9 by 49.2 feet).
The size of the court also differs for amateur basketball players. Many older high school gyms have courts that are 84 feet (26 metres) or even 74 feet (23 metres) in length. High school and junior high courts are 84 feet by 50 feet (26 metres by 15 metres). The size of the court can also vary depending on the specific rules and regulations of the league or tournament. For example, the three-point line distance can differ between leagues, with the international distance being between 6.6 metres (21.65 feet) and 6.75 metres (22.15 feet).
The shape of the court is rectangular, with baskets at each end. The baskets are always 10 feet (3.05 metres) above the floor, except in youth competitions. Indoor basketball courts are typically made of polished wood, usually maple, while outdoor courts are generally made from materials such as concrete or asphalt.
The court has several foundational components, including the baskets, three-point arcs, free-throw (or foul) lines, and the half-court line. There are also circles on the court, including a centre circle and two circles at each end, centred on the foul line. The "key", also known as the free throw lane or "the paint", is 16 feet wide for the NBA and FIBA, and 12 feet wide for college, high school, and junior high play.

Basketball size and weight
Basketballs usually range in size from a few inches in diameter to extra-large balls nearly 2 feet (60 cm) in diameter used in training exercises. The size of a basketball depends on the age, gender, and level of play of the players.
For boys and girls between the ages of 4 and 8, the recommended basketball size is between 22 and 24.5 inches in circumference, depending on the individual's hand size. Middle school boys (or those aged 12-14) use a 28.5-inch ball, while girls of the same age use a slightly smaller ball, with a circumference of 27.5 inches. This size is also recommended for female players aged 12 and above.
The standard size for a basketball in the NBA is 29.5 inches (75 cm) in circumference, while the WNBA uses a slightly smaller ball with a maximum circumference of 28.5 inches (72 cm). This size is also used in men's college and high school basketball leagues. The NCAA men's ball has a maximum circumference of 30 inches (76 cm), while the women's ball has a maximum circumference of 29 inches (74 cm).
The weight of a basketball is also important, in addition to its size. In the NCAA, the men's ball has a maximum weight of 22 ounces, while the women's ball has a maximum weight of 20 ounces. The NBA and WNBA use the same pressure regulations, with a required inflation pressure of 7.5 to 8.5 PSI.
Basketballs are spherical and nearly always have an inflatable inner rubber bladder, wrapped in layers of fiber and covered with leather, rubber, or a synthetic composite. The surface of the ball is divided by "ribs" that are recessed and generally a contrasting color to the ball. An orange surface with black ribs is the traditional color scheme, but basketballs are sold in various colors.

Player positions
In basketball, there are five players on the court for each team at any one time. Each player is assigned to a different position, defined by the strategic role they play. The three main position categories are guards, forwards, and centers. The standard team features two guards, two forwards, and one center.
The guards are typically called the "back court" and the forwards and centers the "front court". Over time, as the sport has evolved, each of the guards and forwards has become more specialized. Today, each of the five positions is known by a unique name and number: point guard (PG) or 1, shooting guard (SG) or 2, small forward (SF) or 3, power forward (PF) or 4, and center (C) or 5.
The point guard, often the team's best dribbler and passer, runs the offense and usually has a high number of assists. They are often referred to as dribblers or playmakers. Point guards are usually between 5 feet 10 inches (1.78 m) and 6 feet 4 inches (1.93 m) tall. They can be scoring point guards, who shoot accurately from three-point or mid-range distance, or facilitator-type point guards, who have a high basketball IQ and can see plays happening before they occur.
The shooting guard, also known as the two or the off guard, is, along with the small forward, often referred to as a wing because of its use in common positioning tactics. Shooting guards are prolific from three-point range and long mid-range. They must be able to correctly space the floor and find open space for themselves.
The small forward, also known as the three, is considered the most versatile of the five positions. They play against small and large players and roam all over the court. Small forwards can score from long shots and close ones, and some have good passing skills, allowing them to assume point guard responsibilities.
The power forward does many of the same things as the center, playing near the basket and rebounding and defending taller players. However, they also take longer shots than centers.
The center is the tallest player on each team, playing near the basket. On offense, the center tries to score on close shots and rebound, while on defense, they try to block opponents' shots and rebound their misses. Today, centers can also be classified as power forwards and dominate opponents with their defensive skills, shooting from the high post.

Scoring points
Basketball is a sport that revolves around scoring points by putting the ball through the hoop. The rules for scoring have evolved since the game's inception in 1891, when every successful shot was worth one point. Today, there are multiple ways to score points in basketball, with each shot type and distance from the basket determining the number of points awarded.
Field Goals
Field goals are shots taken from the court during a game. There are two ways to score a field goal: from inside or beyond the three-point line. A field goal made within the three-point line is worth two points and can be achieved through jump shots, layups, or dunk shots. Layups are running shots taken when the player is close to the basket, while dunk shots involve the player slamming the ball into the basket from directly underneath it. Jump shots, on the other hand, are taken from a greater distance away from the basket.
Three-Point Baskets
A field goal made from beyond the three-point line is worth three points. Introduced by the NBA in the 1979-80 season, the three-point line rewards players for making shots from longer distances. If a player makes a three-point shot and is fouled in the process, they get an additional free throw, resulting in a potential four-point play.
Free Throws
Free throws are awarded to a player after a foul has been committed by the opposing team. The player who was fouled gets one or more free throw attempts, depending on the severity of the foul. A successful free throw is worth one point. In the NBA, if a team commits at least five fouls in a single quarter, the opposing team gets two free throws for any subsequent defensive or loose ball fouls.
Strategies for Scoring
To be effective at scoring in basketball, it is important to utilize players' strengths to get to the free-throw line and make a competitive percentage of three-point shots. Coaches can calculate the Effective Field Goal Percentage (EFG%) to evaluate players' scoring contributions, taking into account the weight of two-point and three-point shots made. However, EFG% does not consider missed free throws or turnovers, which can be deciding factors in a game.

History of the NBA
The National Basketball Association (NBA) was formed in 1949 following the merger of two rival organisations: the National Basketball League (NBL), founded in 1937, and the Basketball Association of America (BAA), founded in 1946. The BAA was the first league to play primarily in large arenas in major cities. The NBA later adopted the BAA's history and considers its founding date as June 6, 1946.
Prior to the merger, the BAA and NBL competed with each other, with the BAA luring away several teams from the NBL, including the Fort Wayne Pistons and the Minneapolis Lakers. However, the NBL gained several players, including Dolph Schayes, and created the Indianapolis Olympians. With financial difficulties facing several teams, the two organisations agreed to merge in 1949, with the president of the BAA, Maurice Podoloff, becoming the president of the newly formed NBA.
In 1950, the NBA consolidated to eleven franchises, a process that continued until 1954-55, when the league reached its smallest size of eight franchises: the New York Knicks, Boston Celtics, Philadelphia Warriors, Minneapolis Lakers, Rochester Royals, Fort Wayne Pistons, Milwaukee Hawks, and Syracuse Nationals. All of these franchises remain in the league today, although some have relocated.
The Boston Celtics dominated the NBA in the 1960s, winning eight straight championships from 1959 to 1966—the longest championship streak in the history of American professional sports. The team was led by center Bill Russell, who joined the Celtics in 1957, and guard Bob Cousy, and coached by Red Auerbach. The Celtics' dominance continued into the late 1960s, with the team winning nine out of the ten championship banners of the decade.
In 1976, the NBA absorbed four teams from the American Basketball Association (ABA), which disbanded that year, adding these franchises to the league.

Frequently asked questions
The 5 sources in basketball are: Point Guard (PG) or 1, Shooting Guard (SG) or 2, Small Forward (SF) or 3, Power Forward (PF) or 4, and Center (C) or 5.
Point Guards are usually the fastest players on their team. They organize the team's offense by controlling the ball and ensuring it gets to the right player at the right time. They are also responsible for involving teammates in offense, executing plays, and leading the team.
Shooting Guards are prolific from a three-point range and long mid-range. They must be able to stay free and correctly space the floor to find open spaces for themselves while their teammates pass the ball around. Efficient communication with teammates is also vital for Shooting Guards.
