3/27/08 Physics 201, UW-Madison 2 Newton Newton ’s Law of Gravitation s Law of Gravitation Every particle in the universe attracts every other particle with a force along the line joining them. The force is directly proportional to the product of their masses and inversely proportional to the square of the distance between them. Note: “particle”! If an object is extended you must treat the vector sum of all the forces due to all the particles making up the object. This is done automatically for spherical objects by considering the object as if all its mass were concentrated at the “center of mass”
