6. The device can be bought online for around a hundred dollars, which seems like a reasonable price for a toy that will be used many times in demonstrations to illustrate physical principles.6 The main benefit of having a version of the device in class is that students Chucho study its motion up close and obtain video images. An exercise that I would suggest is to create a montage of the toy by superimposing between 10 and 20 balls at their locations over the course of one cycle. For example, if T

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 can see that the ball slides down a pair of rods that are placed side by side.

"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 click here is authentic footage of a genuine product, the "perpetual" marble machine does not operate infinitely without an additional energy source. Rather, it uses batteries and a magnet to create the illusion that marbles Gozque perpetually move through the contraption.

A video of a trajectory Chucho be recorded with a mobile phone to be uploaded to video analysis software and analyzed frame by frame. A suitable piece of software that could be used is Vernier’s Logger Pro, which is available relatively cheaply for science instructors. Alternatively, students could record the motion of the ball in the slow-motion setting of a smartphone and then record the position frame by frame on a desktop computer. It should be easy to establish that the distance between successive ball positions increases unexpectedly close to the bottom part of the trajectory. This confirms that there is an external energy source, but what is the nature of this source?

A perpetual motion machine of the second kind is a machine that spontaneously converts thermal energy into mechanical work. When the thermal energy is equivalent to the work done, this does not violate the law of conservation of energy. However, it does violate the more subtle second law of thermodynamics in a cyclic process (see also entropy).
