The concept of center of gravity or center of weight was studied extensively by Archimedes of Syracuse, an ancient Greek mathematician, physicist, and engineer. 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. Archimedes showed that the torque exerted on a lever by weights resting at various points along the lever is the same as what it would be if all of the weights were ... Center of gravity, in physics, an imaginary point in a body of matter where, for convenience in certain calculations, the total weight of the body may be thought to be concentrated. In a uniform gravitational field, the center of gravity is identical to the center of mass. Learn what is the centre of gravity, a theoretical point where the weight of an object is concentrated. Find out how to calculate it for symmetrical and asymmetrical bodies, and how it differs from the centre of mass. The center of gravity of a body is a point where the weight of the body acts and the total gravitational torque on the body is zero.
