Acceleration due to Gravity variation with depth within the Earth[ ]


Acceleration due to gravity of the earth depends on the mass and distance of object from the centre of mass of the Earth. In fact acceleration due to gravity varies with density and distance from centre. Since our earth is non-uniform and the vertical mass distribution within the earth is heterogeneous, with increasing depth, density of the earth increases, although the distance of a particular point from centre decreases. But somewhere increasing density is more effective than the distance, so it increases somewhere, so that acceleration due to gravity firstly increases up to certain distance and then decreases, again increases and finally from core mantle boundary it decreases and become tending to zero at the centre of the earth.
