When is the ball considered in play on a penalty kick?

The ball is considered in play on a penalty kick when the ball is kicked and moves forward. This is pivotal because the laws of the game specify that a penalty kick must be taken from the designated spot, and the kick is only considered valid once the player executing the penalty has made contact with the ball in a manner that propels it forward. This action indicates the start of play for that particular kick, and only then can other players, including those from the defending team, react and engage in the play.

Understanding the moment the ball is in play is crucial for all players, especially the goalkeeper, as they must remain aware of the timing to be prepared for any shot on goal. This clarity ensures that all participants know when the penalty kick is officially underway, maintaining the flow and fairness of the game.
