(p) The force between two masses is directly proportional to the product of the masses.

(q) The force between two masses is inversely proportional to the square of the distance between them.

(r) The acceleration with which an apple falls towards the earth is the same as that with which the moon falls towards the earth, assuming they are at the same distance from the earth.
