Gravity of Earth or (). Gravitational acceleration contributes to the total gravity acceleration, but other factors, such as the rotation of Earth, also contribute, and, therefore, affect the weight of the object. Gravity does not normally include the gravitational pull of the Moon and Sun, which are accounted for in terms of tidal effects. It is a vector (physics) quantity, whose direction coincides with a plumb bob. A non-rotating perfect sphere of uniform mass density, or whose density varies solely with distance from the centre (spherical symmetry), would produce a gravitational field of uniform magnitude at all points on its surface. The Earth
Partial/total eclipses on the Moon on Earth as a partial lunar eclipse, unlike the Earth where a total eclipse only occurs in a small spot while the remainder of a solar eclipse are total, on the Moon, a part is shown as partial and a part is shown is total as the center of the Earth's shadow's coverage totality is more larger than the Moon on Earth. In some eclipses, about 15-20% of a surface of the moon covered by the center of the Earth's shadow sees totality where the Earth eclipses the sun, some eclipses has about 75-80% of the surface covered by the
