in regular earth atmospheric conditions, about sea level,
lets say someone throws an object, that weights 500g,
as hard as he can.
in mid-air, the object starts gaining mass, over.. say 5 seconds, until its got a mass of about 300kg.
will the now 300kg object fly as far, as a 500g object would,
or would it fall short?
i would think for the 300kg object to travel the same distance as the 500g object, it would have to gain energy, as well as mass, but on the other hand,
earths gravity has the same pull on all objects regardless of mass.
so would the object slow down in midair as it gained mass, and slump down from the sky, or would it travel the full distance of a much lighter object?
