[QUOTE="glass, post: 8645281, member: 12251"] Can be, and is. g [I]absolutely[/I] changes, it just does not change enough to worry about for the most part, so for our current purposes we can treat it as a constant. That aside, I cannot really follow what you are saying so instead of trying to rebut it in detail I will just lay out in a bit more detail how it actually works and challenge you to rebut me: [spoiler=The physics]Force is equal to mass x acceleration (F = ma), therefore a = F/m. Force due to gravity = strength of gravity x mass (F = mg). This you got right. Therefore, aceleration due to gravity = mass x strength of gravity divided by mass. Mass, being both on top and bottom of the equation, cancels (a = gm/m = g). Therefore, acceleration due to gravity (neglecting air resistance) is independant of mass.
