In orbit mechanics, the angular momentum is also an important quantity governing thesatellite's motion. Assume planar motion, a satellite is orbiting around Earth centerwithin a fixed plane. Thus it's motion is completely described by the distance r and theangle (relative to some reference direction).êo0(center of Earth)êrPO..P (satellite)satellite's trajectoryObtain the satellite's angular momentum with respect to Earth center. For spacecrafts,the angular momentum (h) is h = Fx, it is independent of mass. What is the magnitudeof h?
