Physical coordinates as dynamic variables for the superparticle from its   geometrical action
  We show that the particle actions in the superspace that are invariant with respect to general covariance transformations can be formulated in terms of physical coordinates with non zero evolution Hamiltonians by identifying these coordinates with some dynamic variables. The local kappa -symmetry for superparticle actions in this formulation is briefly discussed.
