is gravity different depending on where you are in the world?

Answer 1

Yes, there is a difference in gravity though it is very subtle and you would not be able to detect the changes.

A map was created and publish recently. Look at the link below for a nice rotating image. It's not as simple a distance away from the centre of the planet but is a function of the mass directly beneath you, including the thickness of the crust and mantle, etc, etc.

Answer 2

Sir or Madam:

The commonly accepted measure of the pull of gravity
is 9.81 meters per second per second. That number
actually varies some depending upon the makeup of the soil and deep strata underneath where you stand. If, for example, your area has a very high iron content in the subterranean earth the effects of gravity will be somewhat stronger than those over deep sand and limestone subsurface structures. The change is minimal for all practical purposes. Similar slight changes may be noted when moving to high mountain altitudes, or descending deep into the ocean (closer to the core).

As long as George W. Bush is our President there will be no major changes in the Earth's gravitational field.

Answer 3

They found that the Earth's gravity altered, in an instant, by as much as is expected from six years' worth of melting at the Patagonian Ice Fields in southernmost South America. (The Sumatra earthquake in December 2004)

It may seem surprising that Earth's gravity is not equally strong at all points of the globe. Instead, it varies by a small fraction due to the presence of such things as mountains or deep ocean trenches.

The tides and ocean circulation patterns also affect the gravity, as does the rotation of the Earth itself, which bulges out the planet's equator and makes its diameter 21 kilometres wider than the pole-to-pole distance.

Answer 4

Yes - The force of gravity diminishes the further you get from the centre of the Earth. So the higher up you are, the less effect gravity has on you.

Not enough to notice though!

Answer 5

the above answers are right, it does vary with vertical location, but just to add, it is also affected by the mass of the underlying bedrock on which you are standing, igneous rock for instance being denser, will lead to a slight increase in gravity in it's immediate vicinity over, say, sandstone, or another sedimentary rock. Geologists actually map this, and it is called a gravimetric survey.

Answer 6

Not, Particularly Countries but height yes, If you were in Australia it would be No, because gravitation (gravity) pulls mass to the centre of the earth.

Answer 7

The earth is an oblate spheroid. In simpler terms because it spins it is flattened. This means there is less mass below the poles than at the equator therefore gravity is less at the poles than at the equator.

Answer 8

No not at all if it was different some things would be floating in some places. Same gravity levels in the whole globe.

Answer 9

It's slightly different....
If you applied Laplace's Equation in spherical coordinates you can get an expression for g:
g = 9.78049(1 + 0.0052884*sin²(L) - 0.0000059*sin²(2L))
where L is latitude.
The reason theoretical g changes from one latitude to another is because the rotation of the Earth.

Answer 10

Yes...Especially if u're in the water and air then the gravity force is not as powerful as when you're on land
