Abstract:
A method for reducing the momentum of an oscillating body that moves to and from at least one zenith, the method comprising the steps of:(a) placing a mass at a launch area connected to the body, wherein the launch area is spaced-apart from a landing area that is connected to the body;(b) as the body moves toward the zenith, accelerating the mass away from the launch area and toward the landing area to impart on the body a first reactive force component in a direction opposite to that of the body's motion; and(c) allowing said mass to reach the landing area after the body has past the zenith and is moving away from the zenith, so that the arrival of the mass at the landing area imparts on the body a second reactive force component in a direction opposite that of the body's motion; whereby the combination of the first and second reactive force components imparts a net reduction in the momentum on the body.
