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 Foreign Languages Dalian University of Foreign Languages Dalian University of Foreign Languages (DLUFL; ) is a public university in Dalian, Liaoning, China and one of the top foreign language institutes in mainland China. Formerly known as Dalian School of Japanese Language, DLUFL was founded in 1964 with the help of the late Chinese Premier Zhou Enlai. It is now under the administration of the Education Commission of Liaoning Province. Through 40 years of development, DLUFL has fledged into a multi-disciplinary foreign language university which also offers programs in other fields like arts, economics, management, engineering and law. In 2007, the university moves
