Gravitational force acts on all bodies in proportion to their masses. Why, then, doesn't a heavy body fall faster than a lighter body?
A 2 -kg mass is 1m away from a 5 -kg mass. What is the gravitational force (a) that the 5-kg mass exerts on the 2 -kg mass, and (b) that the 2 -kg mass exerts on the 5kg mass? If both masses are free to move, what are their respective accelerations if no other forces are acting?

- Newton's Law of Gravitation can be used to show that if an object weighs w pounds on the surface of the earth, then its weight at a distance x from the center of the earth is W(x) : wR?
