CONSIDERATIONS IN PLANETARY AND SATELLITE MOTION Consider a body of mass m moving with a speed v in the vicinity of a massive body of mass M‚ where M >> m. The system might be a planet moving around the Sun‚ a satellite in orbit around the Earth‚ or a comet making a one-time flyby of the Sun. If we assume that the body of mass M is at rest in an inertial reference frame‚ then the total mechanical energy E of the two-body system when the bodies are separated by a distance r is the sum of the kinetic energy

(See pages 38 and 39 of your textbook.) Newtonian’s form of Kepler’s law extends Kepler’s law by adding the three laws of motion and the law of gravity which in turn extended the application of mapping orbits to more than planets.

As he reaches his closure he states‚ “ The older I get‚ the more things I gotta leave behind.” His emotions (pathos) sets in when he comet to the end of his argument and he tries to give it his all to overturn the commission.
