We use numerical N-body simulations in order to test whether the kinematics of stars and brown dwarfs at birth depend on mass. In particular we examine how initial variations in velocity dispersion can affect the spatial distribution of stellar and substellar objects in clusters. We use "toy" N-body models of a Pleiades-like cluster in which brown dwarfs have their own velocity dispersion which is k times larger than the stellar one.
