Principle of Conservation of EnergyTotal energy of an isolated system always remains constant. Since, the universe as a whole may be viewed as an isolated system, total energy of the universe is constant. If one part of the universe loses energy, then other part must gain an equal amount of energy. The principle of conservation of energy cannot be proved as such. However, no violation of this principle has been observed.A body of mass 5 kg is thrown vertically up with a kinetic energy of `490J`. The height at which the kinetic energy of the body becomes half of the
