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. This kind of machine is impossible, since its existence would violate the first and/or second laws of thermodynamics.
Perpetual motion, the action of a device that, once set in motion, would continue in motion forever, with no additional energy required to maintain it. Such devices are impossible on grounds stated by the first and second laws of thermodynamics. Learn more about perpetual motion in this article.

El móvil perpetuo (en latín: perpetuum mobile) es una máquina hipotética que sería capaz de continuar funcionando eternamente, después de un impulso inicial, sin necesidad de energía externa adicional. Se basa en la idea de la conservación de la energía.
31 de ago. de 2016 · For centuries, people have been trying to invent perpetual motion machines. The laws of physics, though, are working against them.

23 de ago. de 2023 · And what about a perpetual motion machine of the third kind, with zero friction and in a perfect vacuum without producing any usable energy? It won’t work either; atoms in motion dissipate their energy over time. Superconducting materials, with zero resistance, require more energy than they produce.
Perpetual motion machines are devices that are purported to create useful work for “nothing” by violating some physical principle. Generally they are divided into two types, perpetual motion machines of the first and second kinds.
Perpetual Motion: The Holy Grail of Mechanical Engineering | UT Austin Executive Education. Imagine a device so efficient that, once activated, it would work until the eventual heat death of the universe. This is the idea behind perpetual motion, a concept that has fascinated and confounded mechanical engineers for hundreds of years.
