Here is a simplified laymanized. answer given to me one time. Often for practical purposes, center of mass and center of gravity are considered the same on "earth".

If you were falling into a "black hole", pull of gravity on your feet may be much stronger than on your midsection. Midsection stays "center of mass". Feet become "center of gravity".

I'm sure you'll get a much better answer from others here.

center of mass and center of gravity different in non uniform gravitation field?expl

yes.

The center of mass is often called the center of gravity, but this is only true in a system where the gravitational forces are uniform
