... Newton figured out the 1/r2 dependence, assuming that the celestial objects and the Earth were point particles. By inventing integral calculus he could prove that for a mass m2, outside a spherical mass m1, the force of gravity was as if all of the mass m1 was at the center of the sphere. Therefore ...

... Example, pendulum: In Fig. a, a meter stick swings about a pivot point at one end, at distance h from the stick’s center of mass. (a) What is the period of oscillation T? KEY IDEA: The stick is not a simple pendulum because its mass is not concentrated in a bob at the end opposite the pivot point—s ...
