 In classical mechanics , Newton 's theorem of revolving orbits identifies the type of central force needed to multiply the angular speed of a particle by a factor k without affecting its radial motion ( Figures 1 and 2 ) . Newton applied his theorem to understanding the overall rotation of orbits ( apsidal precession , Figure 3 ) that is observed for the planets, but he did not apply it to understanding the rotation of the planets around the Sun. październik 2013 r. 17:17.
