what is law of universal gravitation

    Mass is the amount of a substance present. It is the same on earth, on the moon, or anywhere else. Weight is the attraction of an object by gravity. The mass of a man is the same whether on earth or on the moon but the weight of a man on the moon is about 1/5 that of the weight on earth because the attraction due to gravity is less on the moon.
