### Variation of g due to height and depth - comparative study ...

Variation of g with height: As altitude or height h increases above the earth's surface the value of acceleration due to gravity falls. This is expressed by the formula g1 = g (1 – 2h/R). Here g1 is the acceleration due to gravity at a height of h with respect to the earth's surface and R is the radius of the earth.
