what is called PERPECTUAL MOTION. is there any machine or instrument in earth or in space ? to prove this.?

Question

motions/ gravitional force/friction/

Answer 1

Friction makes it an impossibility

Answer 2

Interesting often asked perpetual question, it is only fitting it gets a perpetual answer.
First answer these questions how old is the universe?
How long will the universe exist?
How far can electromagnetic energy travel before it slows down or stops. (It might be hard to look back at the so called big bang)
how long has the earth been moving?
how long will the earth continue to move through the universe?
If you dont think the matter that makes up the earth will ever stop moving through the universe than you have a perpetual motion machine.

perpetual motion means to move for an infinite amount of time.

i dont think i will be around for that long so i dont think i could prove it, if i was i might be perpetually answering the question.

Answer 3

Perpetual motion is utterly impossible simply because we cannot force Mother Nature to violate her own laws. It's that simple.

The reason is because it violates the 2nd law of thermodynamics.

What violating the 2nd law of thermodynamics means in this case is that for such a device to work, it would have to be more that 100% efficient. In other words, it would have to produce more energy than it takes to run it so its output would have to exceed its input. This is called FREE energy, since it would be excess energy left over that cost nothing at all to produce since it was created from nothing at all - it just appeared from nowhere.

One example of a perpetual motion device would be a battery that recharges itself from the energy it produces so that the battery would last forever and never run out of power. If this were possible, we could make a flashlight that could recharge its own batteries by using the power produced by those very same batteries.

A perpetual motion electric generator would be able to run itself off it's own power producing an endless source of free energy for the household. You would never ever have to pay a power utility bill again!

Would you seriously believe anyone who claimed to have invented such a device and wanted to sell it to you without first proving that it worked??

If perpetual motion were possible, then we would have unlimited energy to power the world and have little or no dependency on other sources of energy. The oil and electric utility industries would nearly collapse.

Just think of the military implications of such a discovery - if it were possible!

These and similar devices are based on the concept of perpetual motion, but they violate the known laws of physics and this is the reason it cannot be done after hundreds of years of trying.

People who promote bogus perpetual motion or free energy machines profit from the scam by getting ignorant wealthy people with more money than they already need to invest their money in the development of a machine that will never exist. The scammers know this, but the ignorant investors keep supporting it anyway in their quest for even more wealth, much to the scammers' profitable delight.

Greed is the only perpetual motion behind such false claims.

Answer 4

Perpetual motion refers to a condition in which an object moves forever without being driven by an external source of energy.

The term is commonly used to refer to machines which display this phenomenon. In the macroscopic world, perpetual motion is not generally considered to be possible. Perpetual motion machines are a class of hypothetical machines which would produce useful energy in a way which would violate the established laws of physics. No genuine perpetual motion machine currently exists, and according to certain fundamental laws in physics they cannot exist. Specifically, perpetual motion machines would violate either the first or second laws of thermodynamics. Perpetual motion machines are divided into two subcategories, defined by which law of thermodynamics would have to be broken in order for the device to be a true perpetual motion machine.

Answer 5

Perpetual motion is, in a nutshell, motion that does not stop when no energy is supplied. There are 3 kinds:

1. one that requires no energy input

2. one that converts all the energy it has to useful work

3. one that produces more energy than it consumes

All three kinds cannot exist (as of yet), since they all violate the laws of thermodynamics. The first and second ones violate the 2nd law (entropy). The 3rd does not conform to the 1st law. (energy conservation)

The closest we have is the random motion of gas molecules in the atmosphere, but this will eventually stop after several billion years.

Answer 6

Perpetual motion does not exist at present and all of the physical laws deem it to be impossible. That does NOT mean that in the future there will never be an example.

We must never assume that our present understanding of natural events is not evolving and progressing.

It was quoted at the turn of the 20th century that all of the major discoveries in science had been completed - how egotistical - and incorrect - was that assumption?

Answer 7

Perpetual motion is imposible. Anything that looks like perpetual motion as using energy in a subtle manner.

Answer 8

there are those perpetual motion machines (they eventually stop) it's 5 or 6 balls suspended side by side. you pull the end one & let it go. when it strikes the adjacent ball, the ball at the other end moves & strikes it's adjacent ball. it continues for awhile
