Soccer, which is actually football, is the common sports all around the world where there are two teams of 11 trying to get the ball inside of a post. This game is loved by everybody. Soccer's history can be traced back to Han Dynasty in the second century B.C. when a similar game called tsu' chu was played. Several centuries after that japanese game called Kemari began. Much later a violent town game called mob football emerged in Europe during the middle ages which is similar to rugby but the ball is kicked instead of thrown. This game was later turned to football.
The game of soccer is built around the pursuit of scoring goals. Teams move the the ball up and down the field in an attempt to kick it within the goal, a framework that measures 8 feet in height and 24 feet in width at the professional level. The player guarding the goal, the goalkeeper, is the only player on a team typically allowed to touch the ball with his hands. Except during a throw-in, the other players must use their feet, knees, head and chest to control and advance the ball. A regulation game is played in two 45-minute halves.
Eleven players, including the goalkeeper, are allowed on the field at one time for each team. These players must keep the ball in play on a rectangular field that measures between 100 and 130 yards in length and 50 and 100 yards in width. The builders of an individual stadium or field determine the dimensions for their facility based on how close they want the fans to the field, the style of game -- a smaller field provides greater advantage to the technical, rather than fast, players -- and the attendance capacity they hope to manage.
If the ball crosses the goal line, the line creating the width of the field, and the defense touches it last, its opponents are allowed a corner kick. On a corner kick, the ball is placed within an arc laid out at one of the two corners on the side where it went out. A player from the offensive team kicks it from htere, typically aiming towards the front of the goal hoping that one of his players can drive the ball into the goal or sometimes the kicker tries to get the ball in.
Penalty kicks take place if the opposing team player is fouled inside the penalty area, also known as D area, which is 18 yards and in from the goal line. For the penalty kick, the ball is placed 12 yards from the goal line and the fouled team player kicks toward the goal facing only the goalkeeper.
Free kicks occur when the foul is committed usually a player tripping or pushing an opponent in the field. In free kick, a player can shoot the ball towards the goal or to their teammates. the opposing team players should be 10 yards away from the ball. Refree decides whether the freekick is direct or indirect. In case of direct freekick, the palyer can shoot it directly to the goal, if indirect, another player has to touch the ball before shooting it to the goal.
