Variation of ‘g’ due to rotation or latitude 

Let us consider the earth to be a spherical ball of mass ‘M’ and radius ‘R’. An object of mass ‘m’ is at point P at latitude φ, when the earth is not rotating the weight of the object is mg. But earth is rotating with angular velocity ω. So, the object is moving in a circular […]

Variation of ‘g’ due to depth 

Let us consider the earth to be spherical mass of ‘M’ and radius ‘R’. A body of mass ‘m’ is placed initially on the surface and finally taken x distance deep into the earth. We know acceleration due to gravity on the surface of earth is This expression shows that acceleration due to gravity decreases […]
