Chapter 12: Gravitation 12.1 Newton's Law of Gravitation Weight – the force that attracts you toward the earth Newton’s Law of Gravitation : Every particle or matter in the universe attracts every other particle with a force that is directly proportional to the product or the masses or the particles and inversely proportional to the square or the distance between them. = Fg Gm1m2r2 Fg magnitude of the gravitational force m1 and m2 masses of 2 particles r distance between particles G gravitational constant Gravitational forces always act along the line joining the two particles; even when the masses of the particles are different, the two interaction forces have equal magnitude Gr avit at ion a nd Spher ica lly Symmet r ic Bodies The gravitational interaction of any two bodies having spherically symmetric mass distributions (such as solid spheres or spherical Shells) is the same as though we concentrated all the mass of each at its center. Moons, planets, and stars all tend to be spherical
