What is the penalty for accidentally causing a ball to move on the putting green?

When a player accidentally causes their ball to move on the putting green, the rules of golf state that there is no penalty incurred. This is under the principle that the putting green is a special area where certain behaviors are treated differently to encourage play. According to the Rules of Golf, if a ball is moved accidentally, it must be replaced to its original position without penalty. This approach emphasizes that the rules aim to maintain the flow of the game and provide fair treatment to players, especially in situations where an accidental movement occurs. Thus, recognizing the lack of penalty in this scenario is important for players to understand how to navigate similar situations on the course.
