Free Kick
A free kick is an action used in several codes of football to restart play with the kicking of a ball into the field of play. Association football In association football, the free kick is a method of restarting the game following an offence by the opposing side. For more serious offences, such as handball or serious foul play. a direct free kick is awarded, from which a goal may be scored directly against the opposing side. (If such an offence is committed in a team's own penalty area, a penalty kick is awarded instead). For less serious offences, such as offside, an indirect free kick is awarded, from which the ball must touch another player before a goal is scored. American football In American football, after a safety is scored, the ball is put into play by a free kick. The team that was scored upon must kick the ball from their own 20-yard line and can punt, drop kick, or place kick the ball. In professional play, a kicking tee cannot be used – however ...

Free Kick (association Football)
A free kick is a method of restarting play in association football. It is awarded after an infringement of the laws by the opposing team. Direct and indirect free kicks Free kicks may be either direct or indirect, distinguished as follows: * An attacking goal may be scored directly from a direct free kick, but not from an indirect free kick. * Direct free kicks are awarded for more serious offences ( handball and most types of foul play – see below for a complete list), while indirect free kicks are awarded for less serious offences * A direct free kick cannot be awarded in the offending team's penalty area: if a team in its own penalty area commits an offence normally punished by a direct free kick, a penalty kick is awarded instead. An indirect free kick may be awarded for an offence committed anywhere. Procedure Signal The referee signals an indirect free kick by raising the arm vertically above the head; a direct free kick is signaled by extending the arm horiz ...

Lens Arles Avignon 2011
A lens is a transmissive optical device which focuses or disperses a light beam by means of refraction. A simple lens consists of a single piece of transparent material, while a compound lens consists of several simple lenses (''elements''), usually arranged along a common axis. Lenses are made from materials such as glass or plastic, and are ground and polished or molded to a desired shape. A lens can focus light to form an image, unlike a prism, which refracts light without focusing. Devices that similarly focus or disperse waves and radiation other than visible light are also called lenses, such as microwave lenses, electron lenses, acoustic lenses, or explosive lenses. Lenses are used in various imaging devices like telescopes, binoculars and cameras. They are also used as visual aids in glasses to correct defects of vision such as myopia and hypermetropia. History The word ''lens'' comes from '' lēns'', the Latin name of the lentil (a seed of a lentil plant), be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Place Kick
The place kick is a type of kicking play commonly used in American football, association football (soccer), Canadian football, rugby league, and rugby union. Gridiron football Place kicks are used in American football and Canadian football for kickoffs, extra points, and field goals. The place kick is one of the two most common forms of kick in gridiron-based football codes, along with the punt. The punt, however, cannot score points (except in Canadian football where it counts as a single). The place kick is the most common kick used in most indoor football games, including the former North American Arena Football League (AFL); punting was not legal in AFL play. A specialist player named the placekicker is generally the only member of the team who attempts place kicks, and is generally not used for any other role on the team. In the USA's National Football League teams, placekickers are generally able to successfully kick a field goal from at least 50 yards away, although ...

Rugby Union
Rugby union, commonly known simply as rugby, is a close-contact team sport that originated at Rugby School in the first half of the 19th century. One of the two codes of rugby football, it is based on running with the ball in hand. In its most common form, a game is played between two teams of 15 players each, using an oval-shaped ball on a rectangular field called a pitch. The field has H-shaped goalposts at both ends. Rugby union is a popular sport around the world, played by people of all genders, ages and sizes. In 2014, there were more than 6 million people playing worldwide, of whom 2.36 million were registered players. World Rugby, previously called the International Rugby Football Board (IRFB) and the International Rugby Board (IRB), has been the governing body for rugby union since 1886, and currently has 101 countries as full members and 18 associate members. In 1845, the first laws were written by students attending Rugby School; other significant ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Free Kick (rugby Union)
A free kick in rugby union is usually awarded to a team for a technical offence committed by the opposing side. Free kicks are awarded for technical offences such as playing too many players in a line-out or time wasting at a scrum. A free kick is also awarded for making a mark. Once awarded a free kick the team must decide how they wish to play it. * The team may opt to play a place kick, where the ball is placed on the ground by the kicker at a point designated by the referee then the player may take a run up to the ball and kick it downfield but not into touch (law 21.4 (e)). This is very rarely chosen. * They may opt for a drop kick, where the ball starts in the player's hands and is dropped onto the ground whereupon it is kicked downfield on its upward bounce by the player. * They may opt for a punt, where the ball starts in the player's hands and is dropped and kicked without bouncing. * They may opt to play a tap kick. A tap kick is played when the team feel they would ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Australian Rules Football
Australian football, also called Australian rules football or Aussie rules, or more simply football or footy, is a contact sport played between two teams of 18 players on an oval field, often a modified cricket ground. Points are scored by kicking the oval ball between the central goal posts (worth six points), or between a central and outer post (worth one point, otherwise known as a "behind"). During general play, players may position themselves anywhere on the field and use any part of their bodies to move the ball. The primary methods are kicking, handballing and running with the ball. There are rules on how the ball can be handled; for example, players running with the ball must intermittently bounce or touch it on the ground. Throwing the ball is not allowed, and players must not get caught holding the ball. A distinctive feature of the game is the mark, where players anywhere on the field who catch the ball from a kick (with specific conditions) are awarded unimpe ...

Free Kick (Australian Rules Football)
A free kick in Australian rules football is a penalty awarded by a field umpire to a player who has been infringed by an opponent or is the nearest player to a player from the opposite team who has broken a rule. Protocol When a free kick is paid, the player's opponent ''stands the mark'', by standing on the spot where the umpire indicates that the free kick was paid or mark was taken. The player with the ball then retreats backwards so that the ball can be kicked over the player standing the mark; the player must retreat on the angle such that he, the man on the mark and the centre of the attacking goal are in the same straight line. A player receiving a free kick is not restricted to kicking the ball; he can play on by handballing to another player, or run around the mark where the free kick has been paid. Examples of free kicks Free kicks are paid for: * Holding the ball: when the player with the ball is tackled and cannot dispose of the ball legally despite having had ...

Field Goal (American And Canadian Football)
A field goal (FG) is a means of scoring in gridiron football. To score a field goal, the team in possession of the ball must place kick, or drop kick, the ball through the goal, i.e., between the uprights and over the crossbar. The entire ball must pass through the vertical plane of the goal, which is the area above the crossbar and between the uprights or, if above the uprights, between their outside edges. American football requires that a field goal must only come during a play from scrimmage (except in the case of a fair catch kick) while Canadian football retains open field kicks and thus field goals may be scored at any time from anywhere on the field and by any player. The vast majority of field goals, in both codes, are place kicked. Drop kicked field goals were common in the early days of gridiron football but are almost never done in modern times. In most leagues, a successful field goal awards three points (a notable exception is six-man football in which, due to th ...

National Federation Of State High School Associations
The National Federation of State High School Associations (NFHS) is the body that writes the rules of competition for most high school sports and activities in the United States. NFHS's headquarters are located in White River State Park in Indianapolis, Indiana. Member and affiliate associations Over 19,500 high schools belong to associations that are members of the NFHS. Most high schools, whether public or private, belong to their state's high school association; in turn, each state association belongs to the NFHS. However, in states that have separate associations for public and non-public high schools, only the public-school bodies are full NFHS members. For example, the Texas University Interscholastic League (public schools, with non-public schools generally not allowed) is a full member; the largest association governing non-public schools, the Texas Association of Private and Parochial Schools, is an affiliate member, while other governing bodies are not NFHS member ...

National Football League
The National Football League (NFL) is a professional American football league that consists of 32 teams, divided equally between the American Football Conference (AFC) and the National Football Conference (NFC). The NFL is one of the major professional sports leagues in the United States and Canada and the highest professional level of American football in the world. Each NFL season begins with a three-week preseason in August, followed by the 18-week regular season which runs from early September to early January, with each team playing 17 games and having one bye week. Following the conclusion of the regular season, seven teams from each conference (four division winners and three wild card teams) advance to the playoffs, a single-elimination tournament that culminates in the Super Bowl, which is contested in February and is played between the AFC and NFC conference champions. The league is headquartered in New York City. The NFL was formed in 1920 as the America ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fair Catch Kick
The fair catch kick is a rule at the professional and high school levels of American football that allows a team that has just made a fair catch to attempt a free kick from the spot of the catch. The kick must be either a place kick or a drop kick, and if it passes over the crossbar and between the goalposts of the opposing team's goal, a field goal, worth three points, is awarded to the kicking team. The fair catch kick is considered to be an obscure rule and it is rarely attempted. Because most fair catches are made well out of field goal range, and a team making a fair catch has possession of the ball and a first down, it is rarely to a team's advantage to attempt a fair catch kick rather than run a play from scrimmage. A team may attempt a fair catch kick if it makes a fair catch within reasonable range when the clock expires at the end of either half, as a half must be extended in order to allow a fair catch kick attempt. At the professional level, the last successful fair c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Canadian Football
Canadian football () is a sport played in Canada in which two teams of 12 players each compete for territorial control of a field of play long and wide attempting to advance a pointed oval-shaped ball into the opposing team's scoring area (end zone). In Canada, ''football'' may refer to Canadian football and American football collectively, or to either sport specifically, depending on context. Outside of Canada, the term Canadian football is used exclusively to describe this sport, even in the United States; the term '' gridiron football'' (or, more rarely, ''North American football'') is also used worldwide as well to refer to both sports collectively. The two sports have shared origins and are closely related but have some key differences. With the probable exception of a few minor and recent changes, for which there is circumstantial evidence to suggest the existence of at least informal cross-border collaboration, the modern rules of the two sports evolved independentl ...
