Because of gravitational attraction , the escape velocity at the surface of a star , say , will be higher if the star is smaller in size or heavier 恒星质量越大,体积越小,引力的羁绊便越大,所需逃逸速度亦越高。
(physics) the force of attraction between all masses in the universe; especially the attraction of the earth''s mass for bodies near its surface; "the more remote the body the less the gravity"; "the gravitation between two bodies is proportional to the product of their masses and inversely proportional to the square of the distance between them"; "gravitation cannot be held responsible for people falling in love"--Albert Einstein 同义词:gravity, gravitation, gravitational force,
