Is earth's gravity the same everywhere? Or at the poles do objects more or less than the equator?

theoretically it is, as we consider the earth to be a round sphere. it is not a sphere though, thus gravity is less at the equator, or Himalaya, and more at the poles. one can calculate the difference if they want, if we know the exact distance from the center of the earth to the point where we are. going further we would have to take into account the lack or excess of mass due to the landscape (mountains, and/or lakes, canyons) at the area. going further, we would have to take into account the position of other planets, as their mass interferes. a bit further we have to take into account the speed of the rotation of the earth, as it is not constant, and a bit further, the angle of the rotation. a bit further, we have to add the mass that is being added as material from space falls on earth. the list can go on and on, one thing is certain: gravity exists, (well, maybe not inside my head,) but it is not exactly the same everywhere, and it is not exactly the same all the time

"Gravity...is a function of how big they are and how far apart they are. Earth isn't a perfect sphere--it's bumpy. The density of its mass and the distance to that mass varies as you move around Earth's surface. The effect on gravity is small and has mostly to do with the internal structure of Earth and to some extent with its topography.

There's big gravity low off the coast of India, where there are thought to be the remains of some old mantle features associated with the plate tectonics of India that led it to collide with the Himalayas. There's a big high in the South Pacific, also thought to be due to mantle structures. "


So if you're high up above sea level, there might be less gravity, because you're further from the centre of the earth.
On the earth gravity is around 9.81m/s^2, sometimes simplified to 10 (it's easier to do sums with)

0 gravity hasn't been effectively made on earth provided that now....it will be obtainable in the destiny.. yet astronauts are experienced previously they're despatched to outer area in 0 gravity... do not confuse it with cancelling out gravitational rigidity... A freely falling body is asserted to have 0 gravity....that's we can sense no weight when we are falling freely...an social gathering is that we are in a develop on the best of a 100 storied progression and the ropes of the raise breaks,then we can experience 0 gravity till we crash to the bottom and die... that's used to coach astronauts...they use a airplane and keep on with some parabolic direction to create this result...it really is because of the inertial direction of the flight easily wish this allows if you're extra fascinated you could examine extra on the web about it..

There are small, minute differences in gravity over the surface of the Earth. The closer you are to the center of Earth, let's say Death Valley then gravity there would be very slightly greater than if you were on top of Mount Everest. You would never feel any difference however.

There are slight differences over the globe. Gravity doesn't even always pull perfectly down since the Earth's mass is not uniformly distributed. That said, you can consider it uniform for all practical purposes. Those differences only matter if you are doing very precise measurements.

Physics.
The natural force of attraction exerted by a celestial body, such as Earth, upon objects at or near its surface, tending to draw them toward the center of the body.
The natural force of attraction between any two massive bodies, which is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.
Gravitation.
Grave consequence; seriousness or importance: They are still quite unaware of the gravity of their problems.
Solemnity or dignity of manner.

yes it same in every where but if you go up it will be Little till you feel no gravity.

it can't be the same everywhere.
