  The gravitational Poynting vector provides a mechanism for the transfer of
gravitational energy to a system of falling objects. In the following we will
show that the gravitational poynting vector together with the electromagnetic
Poynting vector provides a mechanism to explain how massive electrically
charged bodies acquire kinetic energy during a free fall. We will demontrate
that falling electrically charged masses violate the Galilean law of universal
free fall. An experiment is suggested to confirm or not the predicted
phenomena.
