Mechanical energy mechanical energy of the colliding objects has been converted into an equal amount of heat. Thus, the total energy of the system remains unchanged though the mechanical energy of the system has reduced. A satellite of mass formula_4 at a distance formula_5 from the centre of Earth possesses both kinetic energy, formula_6, (by virtue of its motion) and gravitational potential energy, formula_7, (by virtue of its position within the Earth’s gravitational field; Earth's mass is formula_8). Hence, mechanical energy formula_9 of a satellite is given by If the satellite is in circular orbit, the energy conservation equation can be further
Song Instead of a Kiss it to Robert Plant to see if he could duet with her on the song, a move she was furious about. Alannah has cited that it is one of her favourite songs from her catalogue. The song was chosen as the lead single from the "Rockinghorse" album. While Alannah liked the song and found it single-worthy, she was adamant about releasing the uptempo rocker "Our World, Our Times" instead of a ballad as the first single, but was overruled by the record company because they feared the political lyrics of that song would hurt its airplay and chart performance.
