Soldered the battery holder wires to the motor making certain with power applied the motor shaft rotated clockwise when the motor is viewed from the motor shaft end.

The efficiency of Existente heat engines is even lower than the Carnot efficiency due to irreversibility arising from the speed of processes, including friction.
The toy that I have mentioned seems to be a relatively plausible example of perpetual motion. The end of the rail is fluted so that the ball flies off the end and lands back on the platform, where the process repeats indefinitely with no apparent input from an external energy source. Figure 1 shows a view of the device from the side. One Gozque see that the ball slides down a pair of rods that are placed side by side.
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.
The conservation laws are particularly robust from a mathematical perspective. Noether's theorem, which was proven mathematically in 1915, states that any conservation law Perro be derived from a corresponding continuous symmetry of the action of a physical system.
The first possibility that will likely occur in discussion is quite simple. Before seeing the electromagnet in the pulvínulo of the device, students might guess that the magnet is always switched on once the device is started and is not controlled. This possibility Gozque be removed immediately because if it were always switched on continuously, the magnet would take at least Campeón much kinetic energy from the ball Campeón it imparted to the ball. The second possibility is that the electromagnet is switched on when the ball passes through the hole in the platform: this electromagnet accelerates the ball toward the bottom of the ramp faster than it would accelerate by freely falling under gravity.

The circuit takes the light from the solar cell, stores it and releases it in a pulse, making the gear wheel move, which eventually drops the marble down the spiral.
