Principle of Conservation of Energy
Total 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.
`U` is the potential energy, K is the kinetic energy and E is the mechanical energy. Which of the following is not possible for a stable system?
Options:
(a) `U > E`
(b) `U < K`
(c) `E > K`
(d) `K > E`
