Earth's center of gravity
WebGravity is the force that pulls objects towards each other and pulls everything towards the center of the Earth. It is an invisible force. This lesson, Gravity for Kids, teaches you all about this significant pulling force, gravity.

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 is rotating and is also not spherically symmetric; rather, it is slightly flatter at the poles while bulging at the Equator: an oblate spheroid.
