How did nobody before Galileo figure out that all objects fall at the same rate? I don't buy it.

because its counter-intuitive in the face of air resistance. in the atmosphere in normal conditions, a beach ball doesn't fall as fast as a lead ball of same size. now that i've spoonfed you the obvious, you should kys dumb frog

your question was answered
>uniform gravitational acceleration near surface of earth is counter-intuitive in the face of air resistance

because it's lieterally false. friction exists and is non ignorable at all. a feather DOES NOT fall at the same speed than a lead ball, and no, people didnt even know wheather vacuum existed or not back then

because they don't??? Drop a 5 pounds ball and a 50 pound ball and the 50 pounds one falls first because it's heavier meaning more gravity

maybe he was the first to document it (or at least the first we know of). in any case, he got the credit

do you even know how to greentext, you fucking nefag? you cant troll for shit and you obviously never got past highschool, provided you are not still in one
there you go retard. density is non ignorable at all:

I assumed past civilizations could not build narrow, habitable buildings tall enough to test it, but they could have easily dropped things from cliffs.

Even neglecting air resistance, it literally does not.

F=Gmm/r^2

and yet a=F/m=GM/r^2 which approximately constant near the surface of earth regardless of its weight

We were monkeys not that long ago, it wasn't until college physics that I understood universal gravitation.

do it, see what happens. Just drop a full and an empty plastic bottle at the same time.

It was answered. Read deeper history. All this shit we give credit to people longer Galileo was known for quite some time. It wasn't even hidden until recently
