The Football Field
Football is played on a field that measures 120 yards long by 53 and 1/3 yards wide.
There are many components of a football field you should know:
The team on offense is the team with possession of the ball. While on offense, a team is trying to score points with touchdowns or field goals. The center, a player on the offensive line always starts with the ball at the beginning of every scrimmage down. When the quarterback yells hike!, the center throws the ball through his legs to the quarterback to start the play. This is called the snap. The quarterback can pass the ball, hand it off to a running back, or run with it himself for a quarterback-sneak.
The team without the ball is on defense. They are trying to get the ball back, so their team can be on offense. The defense gets the ball back by forcing turnovers. An example of a turnover is an interception, fumble, or turnover on downs. At the start of a down, defensive players drop into coverage or blitz the quarterback in hopes of a sack.
In football, all scoring happens in the end zones. Teams can score points with touchdowns, field goals, and safeties. A touchdown is worth six points and happens when a team brings the ball into the opposing team's end zone. Additional points can be earned after a touchdown by kicking the ball through the uprights for one point, or bringing the ball into the end zone again for two points. Field goals are worth three points and happen when a kicker kicks the ball through the goal post. Field goals can be kicked from anywhere on the field. A safety gives the defense two points and happens when teams make a mistake with the ball in their own end zone.
Football is played over four 15 quarters of game time in regulation. If the score is tied at the end of the 4th quarter, additional quarters of game time called overtime are played to determine the winning team. Teams change possession of the ball after scores, turnovers, and at the start of each half. The offense has four scrimmage downs, or plays at the line of scrimmage to advance the ball on the field. If they fail to reach the first down line, then they must give the ball to the other team for a turnover on downs. Another unit of players called the special teams performs all kicks and returns in football. The special teams is responsible for kickoffs, extra points, field goals, and punts.
