The Science of SoccerSoccer, the world's most popular sport is played by people of all ages around the globe. Like any other sport, many scientific laws and terms are applied to it.

How the game is played Soccer is played by two teams of eleven people on a field a little bit bigger than a football field. The object of the game is to kick the ball into the other teams goal, which is guarded by a goalie.

Newton's 3 laws Newton's 3 laws of motion play a big part in this game. Newton's 1st law says "An object in motion or at rest will remain in motion or at rest until acted upon by an outside force."Ã¯Â¿Â½ This law is displayed when the ball is sent in motion by being kicked. The foot (force) kicks the ball (the object at rest) and sends it in motion until another force stops it.

Newton's 2nd law is the equation force times mass = acceleration. For example: if the ball is kicked with 80 newtons of force, and the ball weighs .45 kilograms the ball would be traveling 36 kilometers per hour.

Newton's 3rd law states that for every action there is an equal and opposite reaction. Again, if a ball where kicked with 80 newtons of force the ball is actually pushing back on your foot with the same amount of force, causing your foot to slow down.

Charles' law Another law that applies to this game is Charles' law. This law states that temperature and volume are concurrently proportional. Meaning when one raises the other does too. This law applies to the ball. When playing a game in cold weather the ball may lose air, due to Charles' law.
