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
Sun and Moon (Middle-earth) and 'died': the Sun after this for a while left its course, burning a large part of Arda the world (apparently creating the deserts of Far Harad). In writings which are older than the material from which the published "Silmarillion" was drawn, the Moon was described at one point as being created by Morgoth as a mockery of Arda the world, but this notion was abandoned. In the Round World version of the legendarium, the Sun and the Moon were not the fruit of the Two Trees, but actually preceded the creation of the Trees. Instead, the Trees preserved the
