Football is a sport played by two teams of 11 players on a 120-yard, rectangular field with goal lines on each end. A football is an oval-like inflated ball usually made of cowhide or rubber.
The offense, or the team with control of the ball, attempts to advance the ball down the field by running or passing the ball, while the opposing team aims to stop their advance and tries to take control of the ball. The offense must advance at least 10 yards in four downs, or plays, or else they turn over the football to the opposing team; if they succeed, they are given a new set of four downs.
The object of the game is for one team to outscore the other. This is accomplished by advancing the football down the field and scoring as many points as possible. Scoring can occur in the form of a touchdown, extra point conversion, two-point conversion, field goal, or safety.Â
