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
Dalian most liveable city in China according to "China Daily". Standard Mandarin is usually spoken in Dalian because it is a city with people from various locations. But Dalian natives use Dalian dialect, which belongs to the Jiaoliao Mandarin subgroup spoken in parts of Shandong and Liaoning provinces. Most of the residents of Dalian were farmers and fishermen who had come from Shandong Province in a large population move, the "Chuang Guandong", during which era Dalian was occupied by the Japanese as the Kwantung Leased Territory. The Dalian dialect incorporates a few loanwords from Japanese and Russian (very rare in Chinese),
