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 University of Technology the "Double First-Rate", "985 project", "211 project" and the "E9 Group" of China. During the last Chinese disciplines assessment in 2017, disciplines including engineering, natural sciences, management, economics, et al ranks highly among Chinese top universities. DUT's business education institutions are accredited by AACSB, CAMEA and EQUIS, one of eight Universities in China. Previously known as Dalian University, DUT was founded in 1949. In July 1950, the School of Engineering separated from Dalian University and became Dalian Institute of Technology (大连工学院, DIT). Due to the rearrangement of the Ministry of Education to enhance development of education and construction of new
