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
Court of Owls Court of Owls The Court of Owls is an organized crime group and secret society appearing in American comic books published by DC Comics, commonly in association with the superhero Batman. They have secretly existed since colonial times in Gotham City. The Court kidnaps child performers from the circus, only to train and transform them into their assassins, known as Talons.
