Earth's center of 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. There are consequentl… WebThe center of gravity of a system is the mean position of an object's or system's weight distribution. Weight is the total force acting on an object due to the gravitational force exerted by an astronomical body. This means that the center of gravity is the point in an object or system where the average of all the weight lies.
