Why can't a perpetual motion machine be made from magnets repelling each other?
The two magnets would push each other apart until friction takes-over, then there'd be no more motion.
No, perpetual motion is prohibited by the laws of thermodynamics. There are machines that might at first seem to be perpetual motion machines but only because their source of energy may not be readily apparent. add. But in economics, inflation serves the purpose of a perpetual motion machine, in which more currency is created continuously. And which serves to illustrate the reality of economics.
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.
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.
What game was created by French mathematician Blase Pascal which he discovered when doing experiments into perpetual motion?
If you are suggesting a "perpetual motion" scenerio, it would violate the first or second laws of thermodynamics. Many inventors dream of perpetual motion machines, but they are an impossible dream according to the laws of thermodynamics. The second law of thermodynamics says that an engine or process of any type must always have an efficiency of less than 100%. A perpetual motion machine that uses a generator to power the motor that runs the…
Perpetual motion would only fit the principle of the conservation of energy if it was a machine that moved that did not have any friction or produce any sound or produce any form of heat or energy that could be lost in any way. Since no such machine is possible to create, as far as we know, perpetual motion is declared an impossibility and does NOT fit the principle of the conservation of energy. Energy…
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.
Perpetual motion is theoretically impossible. In order to have perpetual motion, you would need over 100 percent efficiency and to overcome drag, gravity and friction. When faced with someone who claims to have one, it is often quite difficult to see where they have erred. The patent office insists on a working prototype for this reason. The inventors usually have great zeal and can be quite intelligent, but when pressed for details, refuse to divulge…
