A penalty kick is a method of restarting play in soccer when a foul occurs inside the penalty area. The kick is taken from a designated spot, 12 yards from the goal line, and only the goalkeeper can defend against it. The player taking the kick aims to score by shooting the ball into the goal. During a penalty kick, the attacking player has a clear opportunity to score, as there are no defenders allowed in the area except for the goalkeeper. The outcome can significantly impact the game, making penalty kicks a crucial aspect of soccer matches.
