I think some around here have forgotten there are two types of masses, gravitational mass and inertial mass, even Newton knew this and knew the value of these two things were always exactly the same. That's why two cannonballs with different masses fall to the ground with the same acceleration; although it took Einstein to tell us why these two apparently opposite things, force and inertia, always had the same value. As their name suggests, gravitational mass produces gravity and inertia mass produces inertia. Gravity can be thought of as a force (or is the result of space-time curvature) and a force changes the way an object moves, and inertia resists any change in the way an object moves. So if you multiply BOTH the inertial mass and the gravitational mass by any constant (and you can't change one without changing the other) the result will be absolutely no change in the motion of an object.
