Football (ball) in the context of "Contact sport"

Object manipulation is a form of dexterity play or performance in which one or more people physically interact with one or more objects. Many object manipulation skills are recognised circus skills. Other object manipulation skills are linked to sport, magic, and everyday objects or practices. Many object manipulation skills use special props made for that purpose: examples include the varied circus props such as balls, clubs, hoops, rings, poi, staff, and devil sticks; magic props such as cards and coins; sports equipment such as nunchaku and footballs. Many other objects can also be used for manipulation skills. Object manipulation with ordinary items may be considered to be object manipulation when the object is used in an unusually stylised or skilful way (such as in flair bartending) or for a physical interaction outside of its socially acknowledged context or differently from its original purpose.

Object manipulators may also be practitioners of fire performance, which is essentially object manipulation where specially designed props are soaked in fuel and lit on fire.

Football is a family of team sports that involve, to varying degrees, kicking a ball to score a goal. Unqualified, the word football generally means the form of football that is the most popular where the word is used. Sports commonly called football include association football (known as soccer in Australia, Canada, South Africa, the United States, and sometimes in Ireland and New Zealand); Australian rules football; Gaelic football; gridiron football (specifically American football, arena football, or Canadian football); International rules football; rugby league football; and rugby union football. These various forms of football share, to varying degrees, common origins and are known as "football codes".There are a number of references to traditional, ancient, or prehistoric ball games played in many different parts of the world. Contemporary codes of football can be traced back to the codification of these games at English public schools during the 19th century, itself an outgrowth of medieval football. The expansion and cultural power of the British Empire allowed these rules of football to spread to areas of British influence outside the directly controlled empire. By the end of the 19th century, distinct regional codes were already developing: Gaelic football, for example, deliberately incorporated the rules of local traditional football games in order to maintain their heritage. In 1888, the Football League was founded in England, becoming the first of many professional football associations. During the 20th century, several of the various kinds of football grew to become some of the most popular team sports in the world.

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 ovoid 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 unimpeded possession. Possession of the ball is in dispute at all times except when a free kick or mark is paid. Players can tackle using their hands or use their whole body to obstruct opponents. Dangerous physical contact (such as pushing an opponent in the back), interference when marking, and deliberately slowing the play are discouraged with free kicks, distance penalties, or suspension for a certain number of matches depending on the severity of the infringement. The game features frequent physical contests, spectacular marking, fast movement of both players and the ball, and high scoring.

The goalkeeper (sometimes written as goal-keeper) is a position in association football. It is the most specialised position in the sport. The goalkeeper's main role is to stop the opposing team from scoring a "goal" (i.e. putting the ball over the goal line). This is accomplished by the goalkeeper moving into the trajectory of the ball to either catch it or re-direct it away from the vicinity of the goal. Within the penalty area, goalkeepers are allowed to use their hands, giving them (outside throw-ins) the sole rights on the field to handle the ball. The goalkeeper is indicated by wearing a different coloured kit from their teammates and opposition.

The back-pass rule is a rule that disallows handling passes back to keepers from teammates in most cases. Goalkeepers usually perform goal kicks and also give commands to their defense during corner kicks, direct and indirect free kicks, and marking. Goalkeepers play an important role in directing onfield strategy as they have an unrestricted view of the entire pitch, giving them a unique perspective on play development.

The English word football may mean any one of several team sports (or the ball used in that respective sport), depending on the national or regional origin and location of the person using the word; the use of the word football usually refers to the most popular code of football in that region. The sports most frequently referred to as simply football are association football, American football, Australian rules football, Canadian football, Gaelic football, rugby league football and rugby union football.

Of the 45 national FIFA (Fédération Internationale de Football Association) affiliates in which English is an official or primary language, 43 use football in their organisations' official names, while Canada and the United States use soccer. In those two countries, other codes of football are dominant, and soccer is the prevailing term for association football. In 2005, Australia's association football governing body changed its name from soccer to football to align with the general international usage of the term. In 2006, New Zealand decided to follow suit.

The handball or handpass is a ball-passing skill in the sport of Australian rules football. As throwing the ball is not allowed in Australian football, passing to a fellow player are executed either by kicking, or by a controlled "punch" with one hand holding the ball while the other knocking it into flight (typically in a fashion similar to an uppercut or an underhand volleyball serve). Handballing is the primary means of disposing the ball quickly and over short distances in Australian football.

Handball revolutionized the game in the 1980s, moving it from the classic kick-and-mark style of play (which runs the risk of the pass being contested and intercepted by opposing players) to a fast run-and-carry style that emphasizes maintaining possession and rapid ball movements down the field, which has typified the game since. The most prolific handballers in the history of the Australian Football League: Lachie Neale, Greg Williams, Scott Pendlebury, Josh Kennedy and Adam Treloar have averaged more than 13 handballs a game.
