   Maybe someone out there can answer this one quickly. I hope its
not too fundamental or repetitous.

   Actually, now that I think about it, its really two questions:

   o  Is there a difference between inertial mass and gravitational
      mass. (I believe that is the same as asking,"is there a 
      difference between the effects of gravity and the effects
      of being in an accellerating frame of reference?" But
      Im sure Im making a drastic generalization.)

   o  Given the old "accellerating-elevator-in-space" experiment,
      how can one within the elevator tell the whether he is
      accellerating or under the influence of gravity?


    Any correct answer to these questions will end a heated argument
that is rapidly degenerating into World War III. Can someone save
the world?

                            Thanks in Advance
