doublebounce

The term "doublebounce" can refer to several phenomena, most commonly in the context of physics and ballistics. In the realm of projectile motion, a doublebounce occurs when a projectile strikes a surface, ricochets, and then strikes another surface before coming to rest or continuing its trajectory. This can happen with bullets, balls, or any other object capable of bouncing. The angle and material of both surfaces play a significant role in determining the outcome of a doublebounce, including the direction and velocity of the projectile after the second impact.

In the sport of volleyball, "doublebounce" is a colloquial term used to describe an illegal play where the ball touches the floor twice in succession within the boundaries of a team's court. This typically happens when a player fails to return the ball on the first contact, and it then bounces on the court. It results in a point for the opposing team. The rules of volleyball are strict about the ball not touching the ground within a team's playing area, and a doublebounce is a clear violation.

More abstractly, the concept of a doublebounce can be used metaphorically to describe situations where an idea or action is rejected or fails twice. For instance, if a proposal is rejected by one committee and then subsequently rejected by another, it might be described as a doublebounce. This metaphorical usage highlights the idea of repeated failure or setback.
