Query: How long is a standard basketball court?
The only essential equipment in a basketball game is the ball and the court: a flat, rectangular surface with baskets at opposite ends. Competitive levels require the use of more equipment such as clocks, score sheets, scoreboard(s), alternating possession arrows, and whistle-operated stop-clock systems.
A regulation basketball court in international games is long and 49.2 feet (15 meters) wide. In the NBA and NCAA the court is . Most courts have wood flooring, usually constructed from maple planks running in the same direction as the longer court dimension. The name and logo of the home team is usually painted on or around the center circle.
A game consisted of four 15-minute quarters with a halftime intermission 20 minutes in length. The clock typically only stopped for time-outs, penalties, injuries, and official clarifications. Further stoppages occurred for incomplete passes and out of bounds during the final 90 seconds of the second and fourth quarters. A mandatory official's time-out, called a promotional timeout, was assessed after the first and third quarters and is 90 seconds in duration. Another mandatory official's time-out, called a warning period, was assessed with 90 seconds to play at the end of each half. The game could also be stopped for further promotional time-outs but not exceed 90 seconds per league rules.
The Baloncesto Superior Nacional, which is played under FIBA rules, currently consists of 8 teams, of which the most successful have been Leones de Ponce, Atléticos de San Germán and Vaqueros de Bayamón with 14 titles each. The league has produced players that have distinguished themselves in the NBA, EuroLeague, Spain's ACB, and other tournaments throughout the world. Among them, NBA players Butch Lee, José Ortiz, Ramón Rivas, Daniel Santiago, Carlos Arroyo and José Juan Barea started their careers playing for BSN teams.
The field area is expanded to yards wide and 80 yards long with 20 yard end zones (the same size as an American football field, but with the end zones taking up twice as much of the field as in American football). Games are timed with four quarters of 12 minutes each, including a 15-minute halftime. If the score is tied, a five-minute overtime period is played. If the score remains tied after overtime, a second overtime is played in which the first team to score wins.
A soccer-specific stadium typically has amenities, dimensions and scale suitable for soccer in North America, including a scoreboard, video screen, luxury suites and possibly a roof. The field dimensions are within the range found optimal by FIFA: long by wide. These soccer field dimensions are wider than the regulation American football field width of , or the width of a Canadian football field. The playing surface typically consists of grass as opposed to artificial turf, as the latter is generally disfavored for soccer matches since players are more susceptible to injuries. However, some soccer specific stadiums, such as Portland's Providence Park and Creighton University's Morrison Stadium, do have artificial turf.
Unlike latex-based technology underlying the modern lawn-tennis ball, the game still uses a cork-based ball very close in design to the original balls used in the game. The diameter balls are handmade and consist of a core made of cork with fabric tape tightly wound around it and covered with a hand-sewn layer of heavy, woven, woollen cloth, traditionally Melton cloth (not felt, which is unwoven and not strong enough to last as a ball covering). The balls are traditionally white, but around the end of the 20th century "optic yellow" was introduced for improved visibility, as had been done years earlier in lawn tennis. The balls are much less bouncy than lawn tennis balls, and weigh about (lawn tennis balls typically weigh 2 ounces).
The pitch is rectangular in shape. The longer sides are called touchlines. The other opposing sides are called the goal lines. The two goal lines must be between wide, and be the same length. The two touchlines be between long, and be the same length. All lines on the ground must be equally wide, not to exceed . The corners of the pitch are marked by corner flags.
3v3 Soccer is a variety of soccer played between two teams. Each team may only have three players on the field at a time (hence providing the name, "3 v 3", "3 versus 3", or "3 on 3"). This style of soccer is more commonly referred to as a "small-sided" game, as compared to a full-sided game with larger teams. The field used is smaller than a regulation soccer pitch, instead it typically is 30 yards wide by 40 yards long, although these dimensions vary quite a bit when the game is played indoors due to the varied styles and sizes of indoor pitches. It uses a much smaller goal than full-sided soccer. In most 3v3 there is no keeper, although one variant, 3v3 Micro Soccer, does use a keeper.
Purcell designed a low, bleached-white canvas-and-rubber badminton sneaker for the B.F. Goodrich Company, known as PF Flyers in 1935. The shoe would provide better support on badminton courts because of a steel shank embedded in its heel. For most of the twentieth century, Jack Purcell's tennis sneaker was required wear on all grass and clay tennis courts in the United States and, at least for a time, on newer, all-weather asphalt courts as well. Unlike basketball sneakers (running shoes hadn't been invented yet), Jack Purcell sneakers had perfectly flat soles, unmarred by grooves that could tear up clay or grass and skew the elasticity of tennis ball bounces. Everyone from the youngest learner to professional and amateur tennis stars on the international tour wore Purcell sneakers; no other company made them. In 1972, Converse purchased PF Flyers (now owned by New Balance), along with the trademark rights of Jack Purcell sneakers. When Nike purchased Converse in 2003, Jack Purcell sneakers were kept in production, and is still manufactured today. Purcell-type basketball sneakers are now no different from Converse Chuck Taylor All-Stars, except they have the trademark blue across their toes. Classic Purcell tennis sneakers are unchanged in appearance from their heyday in the 1950s and 1960s, when they were first nicknamed "Blue Tips" and "Smilies", but they have risen in price from about $20 in 1965 to as much as $150 or more today. Converse "Jack Purcell" basketball sneakers are also popular, but more for their vintage fashion appeal than for athletic use.
Football games last for a total of 60 minutes in professional and college play and are divided into two-halves of 30 minutes and four-quarters of 15 minutes. High school football games are 48 minutes in length with two-halves of 24 minutes and four-quarters of 12 minutes. The two-halves are separated by a halftime period, and the first and third quarters are also followed by a short break. Prior to the start of the game, the referee and team captains for each team meet at midfield for a coin toss. The visiting team is allowed to call 'heads' or 'tails'; the winner of the toss is allowed to decide between choosing whether to receive or kick off the ball or choosing which goal they want to defend, but they can also defer their choice until the second half. The losing team, unless the winning team decides to defer, is allowed to choose the option the winning team did not select, and receives the option to receive, kick, or select a goal to defend to begin the second half. Most teams choose to receive or defer, because choosing to kick the ball to start the game would allow the other team to choose which goal to defend. Teams switch goals following the first and third quarters. If a down is in progress when a quarter ends, play continues until the down is completed.
Basketball contests at the 2000 Summer Olympics were held from 16 September 2000 to 1 October 2000. Games took place at the Sydney SuperDome and the Dome in Sydney, Australia. The United States claimed the gold medals in both the men's and women's competitions.
"Law 5: The bat". The bat is no more than in length, no more than wide, no more than deep at its middle and no deeper than at the edge. The hand or glove holding the bat is considered part of the bat. Ever since the ComBat incident, a highly publicised marketing attempt by Dennis Lillee, who brought out an aluminium bat during an international game, the Laws have provided that the blade of the bat must be made of wood.
"Law 6: The pitch". The pitch is a rectangular area of the ground long and wide. The Ground Authority selects and prepares the pitch, but once the game has started, the umpires control what happens to the pitch. The umpires are also the arbiters of whether the pitch is fit for play, and if they deem it unfit, with the consent of both captains can change the pitch. Professional cricket is almost always played on a grass surface. However, in the event a non-turf pitch is used, the artificial surface must have a minimum length of and a minimum width of .
The currently available models have ball capacities of 50-60 balls. Both ball speed range and ball frequencies are adjustable and vary from 30 to 150 km/h and 1.5-12 balls per second, respectively, with the .75 second interval suitable for quick volleys and 10 second interval for other strokes. Changing the speed and frequency of the ball coming out of the machine is intended to help the player to visualize real-game situations where the ball does not always come back into play at the same speed. The adjustable speed is also useful for increasing the speed as the player becomes more skillful.
A game lasts thirty-six minutes, and is split up into three twelve-minute periods. Unlike association football, in professional matches the referee is not the sole arbiter of the end of a period. A separate timekeeping official controls the official game clock, which is stopped for stoppages in play, and typically counts down to zero, as in North American sports such as basketball and ice hockey. Draws are not permitted, with the game going into three minutes of extra time, followed by a penalty shootout if the score is still on level terms after normal time. Unlike football, penalty kicks are decided by sudden death rules.
A rugby union game is divided into two halves of 40 minutes (or shorter for lower-grade games, and breaks given halfway through each half if playing conditions are considered to be extreme) separated by a half time period of up to 15 minutes in an international match. Most notably, a rugby union game will continue after the scheduled end of a half (half-time or full-time) until the ball becomes dead - any occurrence that would have play restart with a scrum or lineout, or when a team scores. This has led to some "nail-biting" finishes where teams losing by only a small margin work their way towards scoring, and games can go on several minutes over time. Something similar can occur at the end of either half in American football, though usually for only a few seconds of additional time, because a play that begins before the half expires continues until the ball is dead regardless of whether there is any time left on the clock. In both sports, the clock is also stopped during substitutions and for injuries, so the referee does not need to add stoppage time as is done in soccer/Association football. American football games are made up of four quarters of 15 minutes each (less at the high school and youth levels), but the clock stops and starts according to specific rules, so that a 15-minute quarter lasts much longer.
Until such time as a special ball is specifically made for elle, tennis balls are used. The fur on the ball could be removed/shaved before use but removing of fur to make the rubber visible is strictly prohibited. A rubber ball or another light ball could be used instead of a tennis ball, but it is of paramount importance that the ball used should be common to both teams.
At all adult levels of the game, a game is 60 timed minutes in length, split into four 15-minute quarters. (High school football uses 12-minute quarters, and the general rule is that the younger the players, the shorter the quarters typically are.) Because of the halftime, quarter breaks, time-outs, the minute warnings (two minutes before the end of a half in the NFL, three minutes in Canadian football), and frequent stoppages of the game clock (the clock stops, for example, after every incomplete pass and any time a ball goes out of bounds), the actual time it takes for a football game to be completed is typically over three hours.
Many companies manufacture and distribute tennis rackets. Wilson, Head and Babolat are some of the more commonly used brands; however, many more companies exist. The same companies sponsor players to use these rackets in the hopes that the company name will become more well known by the public.
Tennis balls were originally made of cloth strips stitched together with thread and stuffed with feathers. Modern tennis balls are made of hollow vulcanized rubber with a felt coating. Traditionally white, the predominant colour was gradually changed to optic yellow in the latter part of the 20th century to allow for improved visibility. Tennis balls must conform to certain criteria for size, weight, deformation, and bounce to be approved for regulation play. The International Tennis Federation (ITF) defines the official diameter as . Balls must weigh between . Tennis balls were traditionally manufactured in the United States and Europe. Although the process of producing the balls has remained virtually unchanged for the past 100 years, the majority of manufacturing now takes place in the Far East. The relocation is due to cheaper labour costs and materials in the region.
The Brooklyn Nets are an American professional basketball team based in Brooklyn, New York. They are a member of the Atlantic Division of the Eastern Conference in the National Basketball Association (NBA). The team plays its home games at the Barclays Center. The franchise was founded as the New Jersey Americans in 1967, and was one of the eleven original American Basketball Association (ABA) teams. In its second ABA season, Arthur Brown, the team owner, moved the team to Long Island and renamed it the New York Nets. The team won ABA championships in 1974 and 1976. When the ABA merged with the NBA in 1976, the Nets were one of four ABA teams admitted into the NBA. The team was moved to the Rutgers Athletic Center in New Jersey; after the 1976–77 NBA season, the team was renamed the New Jersey Nets. Since they joined the NBA, the Nets have won 4 divisional championships, 2 conference championships and appeared in the playoffs 16 times. The Nets moved to Brooklyn in 2012, and now play as the Brooklyn Nets.
The "modern" rules of many football codes were formulated during the mid- or late- 19th century. This also applies to other sports such as lawn bowls, lawn tennis, etc. The major impetus for this was the patenting of the world's first lawnmower in 1830. This allowed for the preparation of modern ovals, playing fields, pitches, grass courts, etc.
Basketball became a popular sport in Puerto Rico, due in part to the BSN, which has been around since the 1930s. During the early 1980s, with many games shown on television, the sport's popularity increased. There is also a women's professional league, which is affiliated to the BSN. Street basketball is also popular among Puerto Rico's youth.
ㅞ is one of the Korean hangul. The Unicode for ㅞ is U+315E.
The game of wheelchair football is played on a standard basketball court — long by wide. The required court markings are a center line and circle, and a key area measuring wide by deep at each end of the court. It can be played either indoors or outside, as long as it meets the standard requirements. All athletes must use either a manual or a power wheelchair when competing in the sport.
Beach tennis merges the world of beach volleyball and tennis. It is related to beach volleyball but played with a tennis ball and paddle racket. The court is a standard beach volleyball court that is 30 feet wide and 60 feet long. There is a center line that splits the court lengthwise. At the center of the court is a 5-foot-10-inch-high (1.78 m) net. A standard tennis racquet or a paddle and a slightly depressurized tennis ball (6 oz instead of 12 oz) are used.
The standard court size in U.S. college and WNBA play is , while the FIBA standard court is slightly smaller at . For most of its distance, the three-point line is from the middle of the basket under both FIBA and WNBA rules. Near the sidelines, the three-point line runs parallel to the.sideline, at a distance of exactly 3 feet in the WNBA and 0.9 m in FIBA play. Under NCAA rules, the three-point distance is for most of the width of the court, with a minimum distance of from the sidelines. The WNBA, FIBA, and NCAA all use a block/charge arc near each basket, with the WNBA and NCAA distance at from the center of the basket and FIBA using a marginally wider radius of exactly .
