A wheel that spins forever; a bird that never quenches its thirst; a clock that never stops ticking, an endless source of free energy. 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. Support Physics Girl videos → https://www.patreon.com/physicsgirl ‪http://physicsgirl.org/ ‪http://twitter.com/thephysisgirl ‪http://facebook.com/thephysic

• A perpetual motion machine tries to produce energy without any energy input. • There are two main types: • Type I: Produces energy from nothing, violating the First Law of Thermodynamics (Conservation of Energy). • Type II: Converts all heat into work with 100% efficiency, violating the Second Law of Thermodynamics. 2. Why It’s Impossible • In the real world, there is always friction, air resistance, and heat loss, which continuously drain energy from the system. • Therefore, no machine can mo
