The Basics of Football

Football

Football is a contact sport where two teams play against each other. Each team is allowed to have 11 players on the field at any one time. Exceeding this number results in a penalty. Players can also make unlimited substitutions, but they can only enter the field after the play is stopped. The rules of football vary by level of play. This article will explain the basics.

Most NFL games involve at least 11 players on the field at a time, though they often substitute players during breaks. Each player has a specific role and performs various actions on the field. A football game generally involves at least one game per week and requires intense physical training. It is also a popular spectator sport, as high school and college teams often attract more than ten thousand spectators.

The biggest goal in football is scoring a touchdown. This can be achieved by carrying the ball across the opponent’s goal line or catching a pass in the end zone. A touchdown is scored when the ball crosses the goal line in front of the goal post. A touchdown is worth six points, and the team scoring the touchdown is given a bonus for extra points. An extra-point attempt is an attempt to convert a touchdown into a field goal.

In addition to scoring touchdowns, teams can score safety points as well. A safety, worth two points, occurs when an offensive player is tackled in the end zone, fumbles the ball, or intentionally grounds the ball.
