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 Institute of Science and Technology Dalian Institute of Science and Technology Dalian Institute of Science and Technology (), is a four-year engineering college, located in Lüshunkou District, Dalian City, Liaoning Province, China. It has its origin in the Information Technology Department, established in 2002, of Dalian Jiaotong University, and became in 2003 an independent school owned by both Jiaotong University and Dalian Sunshine Century Group. It was renamed in 2011 as Dalian Institute of Science and Technology. It has now various departments, such as mechanical engineering, electrical engineering, information technology, software technology, foreign languages (English and Japanese) and fine arts.
