Best Answer

The mass of Earth is about 81 times the mass of its moon, and the gravitational force between two objects is proportional to the product of their masses divided by the square of the distance between their centers.

The Earth and Moon are almost the same distance from the Sun and so it only depends on their masses. The Moon's orbit makes the distance change slightly, so the force varies by about 1%.

What does gravity Change on the body when you leave Earth?

Because gravity is the force of attraction between two objects, and the strength of the force depends on the distance between them. If the Earth is one of the objects and the other one leaves the Earth, then the force of gravity it feels is certainly going to change.


The force of gravity acting upon the mass of an object?

That's usually called the object's "weight". Like say if you're talking about the forces of gravity between you and the Earth, the force of gravity acting on you is your weight on the Earth, and the force of gravity acting on the Earth is the Earth's weight on you, and they're equal.
