The value of 'g':
decreases as we go toward the centre of the Earth
The value of g (acceleration due to gravity) depends on distance from Earth's centre of mass.
Going down into Earth, g decreases linearly with depth and becomes zero at the centre.
Going up above the surface, g decreases with height (not increases); g is maximum at poles and minimum at equator.
Hence, decreases as we go toward the centre of the Earth.
What type of force is responsible for the Moon’s circular motion around Earth?
