Whether gravitational pull of the Earth is equal in all parts of the planet/?

No. In fact, slight variations are useful for mapping out mineral and oil deposits. There are also variations because of mountains, for example. The differences are fairly small: less than 1% of the total force.

No

(1) The shape of the earth is not perfect sphere. Its radius varies from equator to poles that causes variation in gravitational pull.

(2) The density of the earth has lateral as well as vertical variations, this would also cause variation in gravitational pull.

(3) The gravitational pull is maximum at the sea level and as one goes down towards the centre of the earth or away from it, the gravitational pull will change .

thnks

The planet has places that have higher density than other places so yes, there are slight variations.

NASA has to account for these variations in the orbits of spacecraft. The orbits will rise and fall.

No. There are small variations all over the world because the planet;

is not a perfect sphere

is not of uniform density

is affected by tidal pull

Gravity appears less in very deep mines because the ground above you tends to pull you up very slightly.

Gravity varies around the world; therefore, a person's weight varies as well.

At the poles, the force of gravity is approx. one-half of one percent greater than at the equator (9.83m/s^2 vs. 9.78m/s^2). As a result, a person weighing in at 200 pounds at the equator would add about a pound, and would weigh in at about 201 pounds at the poles.

no not at all.it depends on height or depth of the point of observation from the surface of the earth. it decreases as we go into the earth and finally becomes zero at the centre of the earth. in the same way, it decreases as we fly away from the earth surface and thats why astronauts feel weightless in the far space..................

no it differs as the radius changes

Yes they are, you would weigh the same in Antarctica as in America, its the same everywhere

i think its always close to -9.8km/s
