Abstract
We classify all the coadjoint orbits of the central extension Ĝ of the one spatial dimensional Galilei group G. Taking them in support of the generic symplectic realizations of the Galilei group G, we give their possible physical interpretations and also find that mass and force have their origins in the cohomological theory of the Galilei group.
