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 born China, several departments, including Electrical Engineering, Physics and Law, were transferred to other universities and institutions. Meanwhile, scholars from other universities came to enlarge the departments of Chemical Engineering, Mechanical Engineering. The university started to expand right after the rearrangement, attracting more scholars and funding. To ensure future growth, the then-headmaster, Bochuan Qu, strategically moved the university's main campus to the bay area of suburban Dalian. In October 1960, DIT became one of the 26 key national universities directly under the State Ministry of Education. Graduate School of DIT was established in April 1986. In March 1988, DIT changed
