Football is a team sport in which players try to get the ball to the opposing team’s goal. They do so by dribbling it, passing it to teammates, and taking shots. The opposing team has a goalkeeper who protects the goal. In addition, physical contact between opponents is limited. This game is fast-paced and the play stops only when the ball is out of play or when the referee calls a timeout.
In order to score a touchdown, the offensive team has to pass or run the football for at least 10 yards. When the offensive team fails to do so, the other team takes over possession of the ball. If this happens, the team may attempt a field goal, or punt it. During fourth down, teams can only kick the ball if the opposing team is within 40 yards of the goal.
There are several different types of penalties in football. Some of these violations include holding, delaying the game, encroachment, and false start. Offensive players may also be penalized for blocking below the waist. Defensive players must also avoid clipping and blocking below the waistline. In addition, it is illegal for a player to tackle an opponent who isn’t carrying the ball.
The game of football has its roots in ancient history. According to FIFA, it was first played in China during the 2nd and third centuries B.C., although it may have been a distant relative. Some medieval European games have similar rules, but the rules differ by region and period.
