Yeah 😅

g is acceleration due to gravity, is not a constant at all, and varies with height and latitude on Earth.

G is the gravitational constant.

Relationship between the two is:
g = GM/r^2

where M is mass of Earth and r is radius.

That's why g varies, because effective radius of Earth changes with height on the surface, and also with latitude (because Earth is not perfectly spherical, but a slightly flattened geoid shape)
