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 110 yards (101 m) long and 65 yards (59 m) wide attempting to advance a pointed oval-shaped ball into the opposing team's scoring area.
The end zone is the scoring area on the field, according to gridiron-based codes of football. It is the area between the end line and goal line bounded by the sidelines. There are two end zones, each being on an opposite side of the field. It is bordered on all sides by a white line indicating its beginning and end points, with orange, square pylons placed at each of the four corners as a visual aid. Canadian rule books use the terms goal area and dead line instead of end zone and end line respectively, but the latter terms are the more common in colloquial Canadian English. Unlike sports like association football and ice hockey which require the ball/puck to pass completely over the goal line to count as a score, both Canadian and American football merely need any part of the ball to break the vertical plane of the outer edge of the goal line.
In gridiron football, a line of scrimmage is an imaginary transverse line beyond which a team cannot cross until the next play has begun. Its location is based on the spot where the ball is placed after the end of the most recent play and following the assessment of any penalty yards.
In sport, a goal may refer to either an instance of scoring, or to the physical structure or area where an attacking team must send the ball or puck in order to score points. The structure of a goal varies from sport to sport, and one is placed at or near each end of the playing field for each team to defend. For many sports, each goal structure usually consists of two vertical posts, called goal posts, supporting a horizontal crossbar. A goal line marked on the playing surface between the goal posts demarcates the goal area. Thus, the objective is to send the ball or puck between the goal posts, under or over the crossbar, and across the goal line. Other sports may have other types of structures or areas where the ball or puck must pass through, such as the basketball hoop. Sports which feature goal scoring are also commonly known as invasion games.
An ice hockey rink is an ice rink that is specifically designed for ice hockey, a competitive team sport. Alternatively it is used for other sports such as broomball, ringette, rinkball, and rink bandy. It is a rectangle with rounded corners and surrounded by walls approximately 1.22 metres (48 in) high called the boards.
American and Canadian football are gridiron codes of football that are very similar; both have their origins in rugby football, but some key differences exist between the two codes.
Gameplay in American football consists of a series of downs, individual plays of short duration, outside of which the ball is dead or not in play. These can be plays from scrimmage – passes, runs, punts, or field goal attempts – or free kicks such as kickoffs and fair catch kicks. Substitutions can be made between downs, which allows for a great deal of specialization as coaches choose the players best suited for each particular situation. During a play, each team should have no more than 11 players on the field, and each of them has specific tasks assigned for that specific play.
In gridiron football, an official is a person who has responsibility in enforcing the rules and maintaining the order of the game.
A football pitch is the playing surface for the game of association football. Its dimensions and markings are defined by Law 1 of the Laws of the Game, "The Field of Play". The pitch is typically made of natural turf or artificial turf, although amateur and recreational teams often play on dirt fields. Artificial surfaces are allowed only to be green in colour.
The 1933 NFL season was the 14th regular season of the National Football League.
In sports, a hash mark or hash line is a short line/bar marking that is painted perpendicular to the sidelines or side barricades, used to help referees and players recognize on-field locations and visually measure distances. Hash marks serve the same function as the graduated markings on measuring tools such as rulers.
A comparison of American football and rugby union is possible because of the games' shared origins, despite their dissimilarities.
A comparison between American football and rugby league is possible because of their shared origins and similar game concepts. Rugby league is arguably the most similar sport to American football after Canadian football: both sports involve the concept of a limited number of downs/tackles and scoring touchdowns/tries takes clear precedence over goal-kicking.
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 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.
The following terms are used in American football, both conventional and indoor. Some of these terms are also in use in Canadian football; for a list of terms unique to that code, see Glossary of Canadian football.
American football, also known as gridiron, is a team sport played by two teams of eleven players on a rectangular field with goalposts at each end. The offense, the team with possession of the oval-shaped football, attempts to advance down the field by running with the ball or passing it, while the defense, the team without possession of the ball, aims to stop the offense's advance and to take control of the ball for themselves. The offense must advance at least ten yards in four downs or plays; if they fail, they turn over the football to the defense, but if they succeed, they are given a new set of four downs to continue the drive. Points are scored primarily by advancing the ball into the opposing team's end zone for a touchdown or kicking the ball through the opponent's goalposts for a field goal. The team with the most points at the end of a game wins.
The rugby league playing field, also referred to as a pitch or paddock, is the playing surface for the sport of rugby league football and is surfaced exclusively with grass.
Field goal range is the part of the field in American football where there is a good chance that a field goal attempt will be successful.
The conversion, try, or convert occurs immediately after a touchdown during which the scoring team is allowed to attempt to score one extra point by kicking the ball through the uprights in the manner of a field goal, or two points by bringing the ball into the end zone in the manner of a touchdown.
