blems relating to the motion of the earth and other planets-problems which had remained unsolved 'till the Law of Gravitation was discovered by Newton. The Law of Gravitation was not merely a hypothesis but a theory proved by mathematical calculations.
In short, the Law of Gravitation can be enunciated as under "Every material substance attracts every other material substance of the universe with a certain force which is directly proportional to the masses of the two substances and inversaly proportional to the square of the distance between the two " The law can be illustrated by the following numerical example. 'If say, the product of the masses of two substances is 4 units and that of other two substances, separated by the same distance is 20 units, then the force of attraction between the later two will be 2014 which is equal to 5 times that between the former two. In the same way, 'suppose that the distance between two substances is 30 feet and the distance between the other two substances, the product of the masses of which is equal to that of the masses of the former two substances, is say 120 feet In other words the product of the masses in the two cases being the same, the distance apart in the second case is 4 times the distance apart in the first case Hence the force of attraction between the two substances in the second case will be 1/16 times the force of attraction between the two substances in the first case.
From the days of Newton till today, the Law of
