the dropping of the objects on the moon was to prove that when 2 objects are
dropped from the same height in an environment with little or no friction
they will hit the ground at the same time. both bags weigh the same, one is
more bulky and due to size will have a greater inertia because of the energy
needed to move it, both will require the same ammount of work.
course i don't remember the work units or formulas anymore so i may have a
few things off....

belief is a strong thing... of course we all choose what we are going to
