👉 The retrodisplacement effect, also known as the "reverse displacement" or "backward displacement," is a phenomenon that occurs when an object experiences a backward force due to gravity. This force acts in the opposite direction of the gravitational force acting on it, causing the object to accelerate backwards. When an object is thrown upward with a retrodisplacement effect, it will experience a downward force due to the acceleration it has experienced during its journey. This force is known as the "rebound force,"
