”Every body in the universe attracts every other body with a force which is directly proportional to the product of their masses and inversely proportional to the square of the distance between them ”. That is if objects are very close to each other than the distance between them is less and so the force with which they attract each other will be more.
Suppose you have a ball and a box both lying on the floor. Do they actually start moving towards each other? According to the universal law, the ball and the box should be moving towards each other. But in actual this does not happen. This is because the force with which they are attracting each other is very much small.
So here if the mass of the ball is m1 and mass of the box is m2 then, F ∝ m1 m2, and is inversely proportional to the distance between them.
