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
Economy of Dalian There are the Dalian branches of China's five major banks: Bank of China, Industrial & Commercial Bank of China, China Construction Bank, Bank of Communications, and Agricultural Bank of China. Dalian Commercial Bank is now called Dalian Bank, which among other things handles processing of the Dalian Mingzhu IC Card for public transportation. Dalian Commodity Exchange is the only one of its kind in China, expanding the futures market beyond soybeans. A "Financial Street" around the new Commodity Exchange building is now being planned. Since the 1990s, Dalian City has emphasized the development of the IT industry, especially in Dalian
