Question

on which factor gravitational acceleration depends? describe its change with respect to height​

Answer 1

Answer:

1)it depend upon the height and depth from the earth surface .

Gravitational acceleration at a height h is given by

g' = Gmè/(Rè+h)² or

g' = g(1 -2h/Rè)

and at depth it is given by

g' = g(1-h/Rè)

in last equation it show that acceleration due to gravity at the centre of earth is zero.

2) it depend on other factors too.

I.e mass of earth and distance from the centre to that point on earth surface .

I.e it has less value on equator and high value on pole.

pole is more nearer than equator to the surface of earth
