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
Technological and industrial history of China the People's Republic of China). This led to a shortage of skilled personnel that seriously hampered the industrial sector's implementation of imported modern technology and independent development of new management and production forms. In 1980 a modern management training center was established in Dalian, Liaoning, with the help of foreign experts. In 1987 many Dalian graduates found it difficult to use their newly acquired skills because managerial autonomy was lacking, and many cadres had a vested interest in maintaining the status quo. It was then unclear what effect students educated abroad were having on industry. China is well endowed with
