How could I incorperate perpetual motion into my science fair project?

Question

I really wish I could do my project on perpetual motion but the thing is I do not know how to experiment with it. You have to have 10 trials of one experiment and I just do not know how to make it work. I AM NOT TRYING TO INVENT A PERPETUAL MOTION MACHINE. I just want to create an experiment showing why it will not work. Or something along those lines.

Answer 1

If you're serious, you could study the previous attempts, organize them into types, and show their failings. You could learn just enough thermodynamics to discuss intelligently how it applies. You could choose a method you think makes the most sense or has the best chance of succeeding, and design an experiment to test it, even if the experiment couldn't be completed in your lifetime. You could also choose one you could test during the school year, perhaps with a surplus gyrocompass. You could study and discuss things like planetary orbits, electron orbits, and the unattenuated travel of a photon for millions of years, and why they do or do not qualify. Your exhibit could present one candidate as a challenge, and ask the viewer to explain why it is or is not perpetual motion. You'd have a lot of research and a little experiment. You'd have a catchy title, but perhaps not an engaging display.

If you do, I'd appreciate acknowledgement and a copy of your report. If you succeed in finding a useful mechanism, I won't demand any of your profits, but I would like an invitation to your Nobel Prize presentation.

I'm not trying to change your mind, or asking you to expect to invent a PMM. But as you study, keep your mind open and skeptical, and don't dismiss any candidate until you get a solid and rational reason.

Perpetual Motion Science Fair Project

This topic is a little deep for a science fair project. The reason being, in the three concepts of perpetual motion each is so different and uses different sources of energy concepts for each. I think for you to succeed at your science fair project, you would want to show how to prove a concept, not disprove. The thing with perpetual motion concepts is that all but one of the concepts have never been proven and have other laws that contradict them. The third concept of perpetual motion uses (I think) a semiconductor.

Here's a suggestion for a science fair project. Take 10 petri dishes with blood agar in them take a cotton swab from your mouth and a cotton swab from the 10 leading mouthwashes and make an experiment about which one is the best by the least amount of bacteria that grows in the same conditions. Try to keep the dishes at the same temperature as what a mouth would be.

Answer 4

You could recreate a few of the classic perpetual motion machines and show that in 10 trials, they still need more energy to run than they produce. I know that the wikipedia page on perpetual motion machines links to some of the classic designs, dating back to the 1600's.

Answer 5

Sit a girl in a chair and ask her to talk about shopping. Her mouth will demonstrate perpetual motion.

Answer 6

basically have something demonstrating that a frictionless object or environment is impossible, or that having a perfect shape that wont wobble at all when rotated is impossible, there Will always be a Little wobble, so in theory that will drain energy from the system.

Answer 7

do something along the lines of a domino effect and show how there is always an end to the energy exerted by the force given.

Answer 8

When i was in high school i got suspended for my science fair project. I peed in cups and set them under a heat lamp for hours to see what type of bacteria grew in the urine.

Answer 9

you know thjose three balls that swing bck and forth? you could show how energy is lost as it is transferred from 1 ball to another if you know anything about kinetic energy you can totally bullshit it and it will still sound great

Answer 10

keep moving
