Is gravitational pull the same in all parts of the world?

Question

Is gravitational pull the same in all parts of the world?

Answer 1

nope, it's just roughly the same

examples being the pole vs the equator.  since the earth is not perfectly round you weigh more at the pole since you're closer to the centre

or standing above a giant gold mine.  you'd weigh more than standing above a giant empty mine.  because the gravitational force you experience is just the sum of all your atoms being pulled by each of the earth's atoms (as in 1 vs 1 + 1vs 2 + 2vs 2etc), so having a lot of heavier ones nearby would increase the force you feel.  

having said that, withh all the movement in the oceans and under the earth's crust you' weigh slightly differently in the same place at different times!  but none of this would be very significant.  it's probably better to just go on that diet!

Answer 2

Small variations in the force of gravity exist because of the presence of local mass concentrations, such as near a mountain.  Also, the equatorial diameter of the earth is slightly larger than the polar diameter, so gravitational force is higher at the equator.   Actual attraction of a mass to the earth must also take into account the centrifugal force due to rotation of the earth, which counteracts the gravitational attraction, and is strongest at the equator.

Answer 3

Gravitational pullis max at sea level and it changes / lowers down as we move up ward it min at poles  

Answer 4

Scientifically speaking the answer is no. The greater the elevation is the lesser the gravitational pull. This can be explained by:

g=GM/r2    

Where g is acc. due to gravity, G is the Universal Gravitational Constant, M is the mass of Earth and r is the distance between the object and the center of the earth.

As the distances increases, the acceleration decreases,

Since, gravitational pull of the earth=mass *acc , the pull decreases.

Also there is difference in the pull on the poles and the equator. This is because the earth is not a perfect sphere. It is flattened a the poles and bulged at the equator. Therefore the distance varies.

Answer 5

Technically no. The higher elevation you are the less the pull, but it is only very slightly different

Answer 6

not really...it varies from place to place...on top of mountains the pull is less than at sea level..also it varies from pole to pole becuase the earth isn't perfectly circular it's more elliptical
