How is it that creating perpetual motion machines is impossible?

A violation of the laws of physics.



I know that other impossibilities include time travel, telekinesis, and faster than light travel.



Can anyone give me some examples of perpetual motion machines?How is it that creating perpetual motion machines is impossible?it is not impossible



it's very easy to do



and yes it can be done without going anywhere near any 'laws of thermodynamics'......,,,



i know because i made it without trying to, and without any @sshol3s telling me it's 'impossible'



it's easy to do something when people don't tell you 'it's impossible' before you startHow is it that creating perpetual motion machines is impossible?
Who told you it is impossible. These "laws" of physics are nothing but man-made thoughts, and apply only to known science. Impossibility is impossible.

How is it that creating perpetual motion machines is impossible?Any perpetual motion machine is impossible to construct because it would violate one of the laws of thermodynamics. This is easiest to see in the case of the first law.



The first law of thermodynamics states that energy cannot be created or destroyed, and hence, is conserved. If a perpetual motion machine is taken to be a system, and everything else in the universe as its surroundings, the system has a certain amount of total internal energy (including kinetic energy, potential energy, thermal energy, etc.). If the system were to give off energy to its surroundings (so that we could use that energy), it would eventually run out of internal energy. For example, a machine that generates electricity by means of a spinning wheel cannot do so indefinitely, because as its energy is converted to electricity and taken out of the system, the system loses some of its energy, and so the wheel spins ever more slowly. Eventually, it will stop. Even if you don't try to harness the energy of a perpetual motion machine, it's impossible to perfectly isolate the system from its surroundings. Friction dissipates energy; sound dissipates energy; really, almost anything dissipates energy. Thus, even a wheel that isn't being used to generate electricity will eventually come to a halt.
Because in order for one to work, the energy input would have to be %26gt; or = to the energy output. Or, in other words, it would have to be 100% efficient. Since energy is invariably lost through/at various points in the machine, (not lost as in disappear, but as in irretrievable by the machine. That is to say, it goes somewhere that does not contribute to the motion of the machine) the energy would gradually be lost until it reaches the point that the machine has run out of energy.



To loosely demonstrate the principles involved, Get a battery, and connect wire to both ends. While all of the energy should be going back into the battery, some of it is released as heat, and is transferred to the surrounding area.



Now, granted, this isn't a perpetual motion machine, and isn't an attempt to produce one, the principles are the same.How is it that creating perpetual motion machines is impossible?To be specific, it is a violation of the laws of thermodynamics.

Energy can neither be created nor destroyed, merely transformed from one form to another. Also the energy output of any machine will never be equal to the energy input due the machine itself dissipating energy, usually in the form of heat. For perpetual motion the output would need to be equal to the input also described as 100% efficiency.



Consider a spinning top which is given kinetic energy (the energy of a moving body). As the top spins the surface moves quickly past the air around it which causes resistance. Also the point of contact of the top with the floor creates resistance. This resistance causes temperature increases (very small in this case) as the kinetic energy is converted to heat energy also some energy is lost as sound energy. Rub your hand quickly back and forwards repeatedly over a surface and note how your hand warms up. This dissipation of kinetic energy causes the top to slow down and eventually stop.

This is a simple example but the principle remains the same for all machines.



There are a number of ways to minimize the effects of friction from gravity and air resistance but you will never reach 100% efficiency.



And if you should develop the perpetual motion machine then you would become very rich. There is a lot of money resting on the discovery of such a device.How is it that creating perpetual motion machines is impossible?
Closest example I can offer is a new technology in full-frame shock absorbers that work out to be perpetual COUNTER-MOTION systems, where the energies/forces impacted on the assembled structure REDUCES the forces and redistributes them at lower frequencies. The components of this frame system can last for as long as the materials of the frame system ages. These are being tested for force impact strengths, repetitive force impactings and multiple force impactings.
Cats always land on their feet

toast always land butter/jam side down



strap a piece of toast butter/jam side up on a cat's back and throw into air: voila! perpetual motion!!!!



LOL sorry that wasn't a real answer but i someone got a laugh out of it!How is it that creating perpetual motion machines is impossible?
it is created - http://inventions.110mb.com/impossible/perpetum.html



and yesterday I saw a clip of another perpetual motion device but I forgot the address
