GRAV'I-TATE, v.i. [Sp. gravitar; Fr. graviter; from L. gravitas, from gravis, heavy.]

To tend to the center of a body, or the central point of attraction. Thus a body elevated above the earth tends to fall, that is, it gravitates toward the center of the earth; and the planets are supposed to gravitate toward the sun, or center of the solar system.
