Are perpetual motion machines possible?
A wheel that spins forever; a clock that never stops ticking, an endless source of free energy e.t.c. These are but the dreams of inventors striving to make perpetual motion machines, machines that can work forever without any energy input. Are these machines possible without violating the laws of physics? No.
CONSERVATION OF ENERGY
ENERGY CAN NEITHER BE CREATED NOR DESTROYED.
The total energy of an isolated system remains constant irrespective of whatever internal changes may take place with energy disappearing in one form reappearing in another.
