Orbital motion of satellites can be explained mathematically, but orbits of both of natural and artificial satellites do not always remain constant. This clip examines escape velocity and energy of orbital systems, including gravitational potential energy in radial gravitational fields in a variety of situations. Senior-level physics students will find it a valuable resource to enhance their understanding of energy in orbital systems.
