what is the formula for gravity?
as in working out gravity between two objects, given their mass and distance.
hi ithink you maen it:\[F=Gm _{1}m _{2}/r ^{2}\]
That doesn't take into account relativity! But yeah, that's right.
PE=mgh W=mg PE:potential energy W=weight. i dont know which equation did you refer to.
What hosein said is correct. It is the universal force of gravitation.
Thanks. (I'm not studying physics, just doing it for a hobby. I'm not even in grade 11 or 12)
