that’s assuming Earth has uniform gravity, which is not the case either locally (due to changes in density of the composition of the earth) or due to earth bulging at the equator
Less gravity at the equator than the poles because of a combo of the earths bulge and spin
And less gravity at altitude
Granted the difference between pole and equator is like 0.5% and the difference at the peak of Mount Everest and sea level is even less, I just find gravimetry fascinating since I was a kid watching Mythbusters

Is it more or less at the equator? And does altitude affect it?
