Answer:
FOOTBALL FIELD
The football field is 120 yards long and 53 ½ yards wide. At each end of the field and 100 yards apart are the goal lines. The additional 10 yards at each end is the end zone. The field is divided up every 5 yards by a yard line. The middle yard line marker is called the 50 yard line. In parallel to the side lines are rows of hash marks. The football is always placed on or between the hash marks at the start of each play. This ensures that the teams have space to line up on both sides of the football. The position of the football that defines the sides of the ball is called the "line of scrimmage".
There are also goal posts at the back of each football end zone. One way to score is to kick the football through the goal posts. The ball must go between the uprights and over the crossbar.
If any part of a player with the football touches outside the side lines or the end zone it is considered Out of Bounds.
GAME FORMAT
Football is a timed sport. The team with the most points at the end of the time period, wins the game. The game is divided up into 4 periods or quarters with a long "half time" between the second and third quarter. Time is counted while plays are running and sometimes between plays (i.e. time continues after a running play where the player was tackled in bounds, but stops on an incomplete pass). To keep the game going at a good pace the offense has a limited time (called the play clock) between plays.
PLAYERS
The rules in football allow each team to have eleven players on the field at a time. Teams may substitute players between plays with no restrictions. Each team must start a play on their side of the ball.
The defensive players may take any position they want and can move about their side of the football prior to the play without restriction. Although there are certain defensive positions that have become common over time, there are no specific rules defining defensive positions or roles.
The offensive players, however, have several rules that define their position and what role they may take in the offense. Seven offensive players must be lined up on the line of scrimmage. The other four players must be lined up at least one yard behind the line of scrimmage. All of the offensive football players must be set, or still, prior to the play beginning with the exception of one of the four backs which may be moving parallel or away from the line of scrimmage. Further rules say that only the four backs and the players at each end of the line of scrimmage may catch a pass or run the football.
