Q: From time to time people claim to have invented a machine that will run forever without energy input and develop more energy than it uses (perpetual motion). What is wrong with this claim?

Is newtons cradle an example of perpetual montion machine?

No, Newton's Cradle is not an example of a perpetual motion machine. A perpetual motion machine hypothetically runs forever via some external, infinite power source (or, alternatively, it simply requires no additional momentum to continue). However, a Newton's Cradle does not continue forever: its energy slowly falls over time, making it non-perpetual.


Does a perpetual motion machine run forever once you start it?

If they were possible they would, but they aren't.


What would be a machine that can run forever and doesn't need any additional energy?

Who invented the perpetual motion machine?

No one, and no one ever will, since perpetual motion machines are a scientific impossibility.


Who invented perpetual motion machines?

Perpetual motion machines are theoretical only. No one has actually invented one. A perpetual motion machine would have to be able to provide its own source of energy to continue operating.


What is Perpetual Motion Machine first kind?

A perpetual motion machine of the first kind it what we usually mean by a perpetual motion machine. A device which once started will continue to run and do useful work forever without the need to add energy to keep it going. The laws of physics make such a device impossible.


Is it possible to develop a perpetual motion machine?

Theoretically it is impossible. Many have tried and many continue to attempt to develop a perpetual motion machine. Only if there is no friction and no energy is lost to the surroundings, would perpetual motion be possible... No. Such machines are not possible, although until the end of mankind people will perpetually try to imagine or create one.


What is a perpetual-motion machine?

A perpetual motion machine is something that will keep spinning or moving (typically involves rotation, but not always) forever without the need to keep adding energy. These are typically viewed as something that will move forever that we can connect a generator to in order to obtain free infinate energy.
