Perpetual motion is the motion of bodies that continues forever in an unperturbed system. A perpetual motion machine is a hypothetical machine that can do work infinitely without an external energy source.
Learn what perpetual motion is and why it is impossible according to the laws of thermodynamics. Explore the three types of perpetual motion machines and some common myths on them.
- Practically, it is not possible to have a system under perpetual motion.
- Following are the types of perpetual motion machines: Machines of the First Kind Machines of the Second Kind Machines of the Third Kind
- The motion which can be sustained without the need for any external sources of energy is known as perpetual motion.
- False. Perpetual motion machines violate the laws of thermodynamics.
- No, planets are not under perpetual motion.
