  Relativistic dynamics of distributed mass and charge densities of the
extended classical particle is discussed for arbitrary gravitational and
electromagnetic fields. Vector geodesic relations for material space densities
are consequences of tensor gravitational equations for continuous sources and
their fields. Classical four-flows of elementary material space depend on local
four-potentials for charged densities, like in quantum theory. Six
electromagnetic intensities can describe satisfactorily only the simplest,
potential kind of continuous matter motion.
