While actually formulated
While actually formulated by Sturm, Bertrand's theorem deals with a situation when a set of these are applied to a system. One form of it is linked with thrust, thought it is not a force like thrust, and ion thrusters have very high values for this quantity. That form, which is defined per unit of propellant is the specific type of this used to describe the efficiency of a rocket, while in classical mechanics, it is equal to the mass times the change in velocity. For 10 points, identify this term which is classically the integral of force with respect to time or the change in momentum upon impact.
