- n. The point in or near a body at which the gravitational potential energy of the body is equal to that of a single particle of the same mass located at that point and through which the resultant of the gravitational forces on the component particles of the body acts.
- n. The point of greatest importance, interest, or activity: "The center of gravity for the English language is no longer Britain. American English is the greatest influence on English everywhere” ( Robert W. Burchfield).

DEAR PAGE -- I received your last by T. Nelson whom luckily met on my road hither. surely never did small hero experience greater misadventures than I did on the first two or three days of my travelling. twice did my horse run away with me and greatly endanger the breaking my neck on the first day. on the second I drove two hours through as copious a rain as ever have seen, without meeting with a single house to which I could repair for shelter. on the third in going through Pamunkey, being unacquainted with the ford, I passed through water so deep as to run over the cushion as I sat on it, and to add to the danger, at that instant one wheel mounted a rock which I am confident was as high as the axle, and rendered it necessary for me to exercise all my skill in the doctrine of gravity, in order to prevent the center of gravity from being left unsupported the consequence of which would according to Bob.
