Football is a team sport that involves 11 players on each side. The object of the game is to score more points than the opposing team. Points can be scored by throwing and catching the ball into the opponent’s end zone (“touchdown”), or by running with it into their own end zone (two point conversion). The scoring team can also kick the ball through the opposing goal post for a field goal. In addition to being a fun and social activity, football is great for muscular health, cardiovascular health, bone strength, and hand-eye coordination.

American football is a contact sport and can be dangerous if the proper safety precautions are not taken. In the early years of American football, many athletes died from the violence and the game was banned in several cities. However, rules were established over time to make the game safer. Today, the NFL is the biggest professional league for football and is a popular sport to watch.

The modern game of football originated in the United States and is a combination of rugby and soccer. It was first played in schools and later on at colleges and universities. It is believed that a student named William Webb Ellis invented the game by picking up a ball and running with it. This was preferred to kicking the ball because it allowed the player more control of the ball.

Each team has four downs, or attempts, to advance the ball 10 yards downfield and achieve a first down. If they cannot do so, the ball is turned over to the other team and play begins again. The team that does not turn over the ball at the end of the fourth quarter wins the game.
