If the Earth would be a perfect sphere, you would experience no gravity in the center because all the mass around you would pull at you with the same strength in all directions, netting you a zero total force.
Gravity: The attraction between an object on the surface and the center of the earth.
If the object is homogeneous, its center of mass is in its geometrical center. And if it is small compared to Earth, its center of gravity is, for all practical purposes, its center of mass.
At the earth's center, the acceleration/force of gravity is theoretically zero.(At least the force of gravity between the earth and an object at its center. There's still the gravitational forcesbetween the object and everything else ... the sun, moon, stars, etc.)
The surface gravity on Io is very low compared to Earth, due to its low mass, around 0.183g or 18.3% of the Earths pull at the surface. this is just a little more than the surface gravity on our own moon, which is about 16.5% of earths pull.
Because the acceleration of gravity on the surface of any given body depends on the mass of the body and its radius ... the distance of the surface from the center. Mars' mass ... about 11% of Earth's ... and Mars' radius ... about 53% of Earth's ... combine to produce about 38% of Earth's gravitational acceleration at the surface of Mars.
An object on the moon's surface weighs 0.165 as much as it does on the Earth's surface.
Io's surface gravity is about 0.18 g, where Earth's gravity is 1.0 g.
The surface gravity on Mars is about 37% or 3/8 that on Earth.
When compared to the surface gravity of Earth, Neptune has approximately 14% more gravitational pull. This is a small difference when compared to other planets in the solar system.
Surface gravity on mars is 0.376 compared to that of the earth.
Sedna's surface gravity is estimated to be 0.27 m/sec2; Earth's surface gravity is about 9.8 m/sec2.
16.55% as strong on the surface.
No. At the centre of the earth the acceleration due to gravity is ZERO
The moon's gravity is about 1/6th of the earth's.
Uranus has a slightly weaker "surface gravity" compared with the Earth.
The gravity on the surface of Mars is approximately one third of that on the surface of Earth. Comment: I always say "about 38%".
Being smaller, the Moon's gravity is less than that of Earth.
