Abstract:In this work, the mechanism behind motion in closed systems is investigated by studying two simple mechanical systems. Firstly, a simple "ballistic" car system introduces the subject of propulsion as a function of a parameter that modulates the amount of ejected mass, thus allowing a transition between a closed to an open system. The second example provides a physically realizable (and optimizable) system, in which a mass sliding on the internal surface of a mechanical wheeled cavity is shown to produce a net … Show more
