WebNewton, following an idea that had long been discussed by others, said that the closer two objects are to each other, the more gravity will affect them. According to Newton's law of universal gravitation, gravity is a force between any two objects with mass. Three numbers affect its strength: the mass of each object, and the distance between them. trahan family funeral home of milton floridaWebIsaac Newton (1642-1727) later described the law of gravity: All objects in the universe attract each other. This attractive force is proportional to the objects' masses and decreases as the square of the distance separating them.
