Objective and Basic Setup
Soccer, also known as football, is a team sport where two teams of 11 players each aim to score more goals than the opponent by kicking a ball into the opposing team's net. Matches are played on a rectangular field, typically 100-110 meters long and 64-75 meters wide, with goalposts 7.32 meters wide and 2.44 meters high. The game lasts 90 minutes, divided into two 45-minute halves, with a 15-minute halftime break.
Key Components: Players, Ball, and Equipment
Each team fields 10 outfield players and 1 goalkeeper. Outfield players cannot use their hands or arms to touch the ball, except the goalkeeper within their penalty area. The ball must be spherical, with a circumference of 68-70 cm and weight of 410-450 grams. Players wear uniforms, shin guards, and appropriate footwear; no jewelry or dangerous items are allowed. Substitutions are limited to 3-5 per match, depending on the competition.
Practical Example: Starting and Scoring Play
A match begins with a kick-off from the center circle, where the ball must move forward and be touched by another player before the kicker touches it again. To score, the entire ball must cross the goal line between the posts and under the crossbar. For instance, if a player dribbles past defenders and shoots the ball into the net, it counts as a goal, awarding one point to their team. Fouls, like tripping an opponent, result in a free kick or penalty kick if inside the penalty area.
Importance and Common Infractions
These rules ensure fair play, safety, and strategic depth, promoting teamwork and skill development. Common infractions include offside (being nearer the opponent's goal line than both the ball and the second-last opponent when the ball is played), handball (deliberately handling the ball), and dangerous play. Violations lead to free kicks, throw-ins, or cards: yellow for caution, red for ejection. Understanding these rules is essential for players, referees, and fans to appreciate the game's integrity.
