There is a scientific consensus that perpetual motion in an isolated system violates either the first law of thermodynamics, the second law of thermodynamics, or both. The first law of thermodynamics is a version of the law of conservation of energy.
As a distinct composition, perpetuum mobile can be defined as one in which part or most of the piece is intended to be repeated an often unspecified number of times, without the "motion" of the melody being halted when a repeat begins.
Aug 23, 2023 · Perpetuum mobile violates either the first law of thermodynamics (perpetual motion of the first kind, requiring no external energy) or the second law (perpetual motion of the second kind, converting all heat into usable mechanical or electrical energy), or both.

Nov 3, 2016 · A perpetuum mobile of the first kind is one that violates the conservation of energy, i.e. you have to put in at least as much energy as the work you get out. A perpetuum mobile of the second kind violates the second law of thermodynamics, which means that you have to put in more energy than the work you get out.
The history of perpetual motion machines dates at least back to the Middle Ages. For millennia, it was not clear whether perpetual motion devices were possible or not, but modern theories of thermodynamics have shown that they are impossible. Despite this, many attempts have been made to construct such machines, continuing into modern times.
Oct 9, 2018 · The very first know design of a perpetual motion machine dates back to 1150. It is called the Bhaskara Wheel, and was designed by an Indian mathematician Bhaskara II. Over time, people tried to...
