Final answer:
When the ball is not in play, kicking or attempting to kick an opponent with excessive force is considered 'Violent Conduct' and is penalized with a red card.
Step-by-step explanation:
The action of a soccer player kicking or attempting to kick an opponent with excessive force when the ball is not in play does not fall under the category of a 'Serious Foul Play' because the ball is not in play. Instead, this behavior is penalized as 'Violent Conduct'. When the ball is out of play, any violent action directed at an opponent or any other person is considered 'Violent Conduct' and is typically punished with a red card, resulting in the immediate dismissal of the player from the game. It's important for players to maintain sportsmanship and control even when the ball is not in play to avoid severe penalties.
