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.
Aug 31, 2016 · Simply put, the First Law of Thermodynamics states that energy cannot be created or destroyed, only transformed from one form to another. A perpetual motion machine would have to produce work...
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.
There are two types of perpetual motion machines: Perpetual motion machines of the first kind are those devices that violate the first law of thermodynamics, the principle of conservation of energy, creating energy out of nothing. Most attempts fall into this category.
