   The force of earth's gravity acting on the moon is a centripetal force.   
      
   If this is so (if it is the same force), how is one (the centripetal   
   force) real and the other (the gravitational one) apparent?   
      
   [Moderator's note: One good answer is probably enough.  Also, followup   
   questions shouldn't repeat the discussion on this topic here not that   
   long ago.  -P.H.]
