The principles of thermodynamics are so well established, both theoretically and experimentally, that proposals for perpetual motion machines are universally dismissed by physicists. Any proposed perpetual motion design offers a potentially instructive challenge to physicists: one is certain that it cannot work, so one must explain how it fails to work. The difficulty (and the value) of such an exercise depends on the subtlety of the proposal; the best ones tend to arise from physicists' own thought experiments and often shed light upon certain aspects of physics.

Students could verbally express or write on a piece of paper all the things that they notice about the apparatus. They should notice quite quickly that the ball describes a parabolic trajectory when it flies through the air on its way back to the initial upper platform. The highest point of the trajectory (the vertex of the parabola) is higher than this platform, so the ball must have picked up some extra kinetic energy somewhere during the trip through the hole back to the upper platform. The question is where along the way could this have happened and what it is that could have imparted extra speed to the ball. Students should think of how they could potentially figure trasnochado where on the trajectory the ball is being sped up.

"Just perfect! I had a lot of fun assembling the pieces, it even helped keeping two teenagers occupied for an afternoon during our beloved pandemic. Seller was exceptionally nice and helpful, answering all my questions at length.

Context While this is authentic footage of a genuine product, the "perpetual" marble machine does not operate infinitely without an Perpetual Marble Machine Kinetic additional energy source. Rather, it uses batteries and a magnet to create the illusion that marbles Perro perpetually move through the contraption.

Plenty of companies are making toys that create the illusion of perpetual motion. Take this “Perpetual Motion Marble Machine Kinetic Art” for example: it is a tiny marble machine with an electromagnetic mechanism that pushes the ball to the top.

The output work power of heat engines is always smaller than the input heating power. The rest of the heat energy supplied is wasted Triunfador heat to the ambient surroundings. The thermal efficiency therefore has a maximum, given by the Carnot efficiency, which is always less than one.

In some cases a thought experiment appears to suggest that perpetual motion may be possible through accepted and understood physical processes. However, in all cases, a flaw has been found when all of the relevant physics is considered. Examples include:

Vacuum energy and zero-point energy: In order to explain effects such Vencedor potencial particles and the Casimir effect, many formulations of quantum physics include a background energy which pervades empty space, known Ganador vacuum or zero-point energy. The ability to harness zero-point energy for useful work is considered pseudoscience by the scientific community at large.

A heat pump, due to it having a COP above 1: the energy it consumes Ganador work is less than the energy it moves Ganador heat.
