The law that entropy always increases – the second law of thermodynamics – holds, I think, the supreme position among the laws of Nature. If someone points trasnochado to you that your pet theory of the universe is in disagreement with Maxwell's equations – then so much the worse for Maxwell's equations.
The "Overbalanced Wheel", annotated with distances of the weights from the centreline showing that the torques on both sides even pasado on average Gravity also acts at a distance, without an apparent energy source, but to get energy demodé of a gravitational field (for instance, by dropping a heavy object, producing kinetic energy Vencedor it falls) one has to put energy in (for instance, by lifting the object up), and some energy is always dissipated in the process. A typical application of gravity in a perpetual motion machine is Bhaskara's wheel in the 12th century, whose key idea is itself a recurring theme, often called the overbalanced wheel: moving weights are attached to a wheel in such a way that they fall to a position further from the wheel's center for one half of the wheel's rotation, and closer to the center for the other half.

Subsequent analysis (and experiment) have shown there is no way to physically implement such a system that does not result in an overall increase in entropy.
For the purpose of answering this question, I suggest that students should now propose potential mechanisms that explain what is seen and then work through the implications and plausibility of each mechanism. After this, groups of students could argue for or against some of the proposed mechanisms, a technique that reinforces concepts learned earlier in a physics course, but that also requires a deeper understanding of the concepts as opposed to learning by rote or memorization. It would obviously be desirable for students to have access to the toy shown in Ref.
"Just completed the marble run. click here I had to make a couple of adjustments & now it works great. The documentation on the other hand - needs improvement. Some of the illustrations aren't clear. The photos of the wood components are a nice touch - but the color of the wood blends into the background - the white paper of the document. Note for other customers - the spots you place a few of the upright supports in - there's a little wiggle room - ie, the piece is slightly smaller than the placement spot.

/20. This would then allow students to calculate the speed of the ball at different locations along its trajectory and quantitatively confirm the statement above that the ball obtains a burst of speed close to the bottom part of its trajectory.
