Solution for central force model This class of force model generates orbits that are conic sections. We will deal only with closed elliptical orbits The orbit plane stays fixed in space One of the foci of the ellipse is the center of mass of the body These orbits are described Keplerian elements 02/20/02 12.540Lec0502/20/02 12.540 Lec 05 5 Solution for central force model • This class of force model generates orbits that are conic sections.
