The concept of center of gravity or weight was studied extensively by the ancient Greek mathematician, physicist, and engineer Archimedes of Syracuse.He worked with simplified assumptions about gravity that amount to a uniform field, thus arriving at the mathematical properties of what we now call the center of mass.
In physics, if variations in gravity are considered, then a center of gravity can be defined as the weighted mean of all points weighted by their specific weight. In geography, the centroid of a radial projection of a region of the Earth's surface to sea level is the region's geographical center.
The following is a list of centroids of various two-dimensional and three-dimensional objects. The centroid of an object in -dimensional space is the intersection of all hyperplanes that divide into two parts of equal moment about the hyperplane.

The center of gravity of a body is the point around which the resultant torque due to gravity forces vanishes. Center of gravity or centre of gravity may also refer to: Center of Gravity (festival), an annual Canadian sport and music festival; Center of gravity (military), a concept developed by Carl Von Clausewitz, a Prussian military theorist
WASHINGTON (Reuters) -U.S. Defense Secretary Lloyd Austin delivered perhaps his strongest remarks to date on Saturday over Israel's need to protect civilians in Gaza, calling them the center of ...
where the symbol means "is proportional to". To make this into an equal-sided formula or equation, there needed to be a multiplying factor or constant that would give the correct force of gravity no matter the value of the masses or distance between them (the gravitational constant).
