Difference between Acceleration due to gravity at poles and equator

Difference between Acceleration due to gravity at poles and equator

Acceleration due to gravity at poles

1) The magnitude of acceleration due to gravity at the surface of earth is given as,

g = GM/R2

Where, M = mass of earth, R= radius of earth, G = universal gravitational constant and

2) We know that the earth is flattened at poles, so the radius of earth at the poles is small, then the value of acceleration due to gravity can be given as,

gpole = GM/RP2

Where RP = Radius of earth at poles.

3) From comparison of formulae for acceleration due to gravity mentioned in above points, we can conclude that the acceleration due to gravity at poles is more than any other value on earth.

4) Acceleration due to gravity on surface of earth increases as we go towards the pole of earth.

5) As the acceleration due to gravity increases towards the pole, weight of object also increases as we go towards the pole.

Acceleration due to gravity at equator

1) The magnitude of acceleration due to gravity at the surface of earth is given as,

g = GM/R2

Where, M = mass of earth, R= radius of earth, G = universal gravitational constant and

2) We know that the earth is bulged at equator, so the radius of earth at the equator is large, then the value of acceleration due to gravity can be given as,

3) From comparison of formulae for acceleration due to gravity mentioned in above points, we can conclude that the acceleration due to gravity at less than any other value on earth.

4.) Acceleration due to gravity on surface of earth decrease as we go towards the equator of earth.

5.) As the acceleration due to gravity decreases towards the pole, weight of object also decreases as we go towards the pole.
