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.

East of the Sun (and West of the Moon) East of the Sun (and West of the Moon) "East of the Sun (and West of the Moon)" is a popular song written by Brooks Bowman, an undergraduate member of Princeton University's Class of 1936, for the 1934 production of the Princeton Triangle Club's production of Stags at Bay. It was published in 1934 and soon became a hallmark of the Princeton Tigertones, one of Princeton University's all-male a cappella groups. The standard is also sung by the Princeton Nassoons, Princeton University's oldest a cappella group. "East of the Sun" was first recorded by Hal Kemp for Brunswick Records on
