Gravity
Gravity.
The Earth's gravity pulls the Moon towards it and its center.
Acceleration due to the earth's gravity is zero at the center of the Earth because at that point the mass of the earth is equally distributed in all directions, so pulling equally in all directions for a net zero pull. Simplistically, acceleration due to gravity decreases as distance from the center decreases. At the center the distance is zero, hence gravity is zero.
No, it depends only on Earth's mass, and our distance from Earth's center.
Same attraction all directions
Since the atmosphere is more or less symmetric, its center of mass (center of gravity) gravity must be quite close to Earth's center.
center of earth
center of earth
that is gravity
Yes. At least, the gravity resulting from planet Earth.
in the core
No. Earth's gravity is a result of its mass. Every bit of mater on and within Earth contributes to its gravity.
No. At the centre of the earth the acceleration due to gravity is ZERO
That all depends on the shape of the object and how its mass is distributed. The center of gravity of a solid sphere is at the center of the solid sphere. The center of gravity of a solid cube is at the center of the solid cube. The Earth's center of gravity is at the center of the Earth, and there's certainly plenty of mass there. But the center of gravity of a ring is at the center of the ring ... an open space where the finger goes.
The Earth. Actually, technically, the Moon and Earth revolve around a common center of gravity, but that center of gravity falls within the earth itself.
Roughly 3,960 miles from the center of the earth.
