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 Polytechnic University economics. Dalian Polytechnic University Dalian Polytechnic University () is a university in Dalian, Liaoning. The school was founded in 1958 in Shenyang as the Shenyang Institute of Light Industry (). In 1970, it was transferred to Dalian, and renamed as the Dalian Institute of Light Industry (). In 2006, it was promoted in 2006 from the rank of institute to the rank of university. It is the only institution of higher education in northeast of China specializing in light industry, food, textiles and art design. There are about 15,000 students on the campus.
