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.

What is the difference between perpetual motion machines of first kind and perpetual motion machines of the second kind?

Perpetual motion machines of the first kind are hypothetical machines that violate the first or second law of thermodynamics by producing energy without any external source. Perpetual motion machines of the second kind are also hypothetical, but they generate energy by utilizing an external source and converting some of it into work without depleting the source. Both types of machines are not possible based on our current understanding of physics.


Why can't electric suppliers use electric motors to spin the generators?

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 generator requires both the generator and motor to operate with 100% efficiency. This type of perpetual motion machine does not violate the first law of thermodynamics, but violates the second law of thermodynamics. It is a perpetual motion machine of the second kind because it violates the second law of thermodynamics. Not even the cleverest engineer or inventor can build a perpetual motion machine because it would violate either the first or second law of thermodynamics, which are fundamental laws of physics.


What is perpatual motion?

It is the idea of a machine continuously producing energy, without energy input - or producing more energy than what is put into the machine. This would violate the First Law of Thermodynamics (conservation of energy), and in general, it is not believed to be possible. No process is known which violates the conservation of energy. (A "perpetual motion machine of the second kind" would violate the Second Law of Thermodynamics; this is generally believed to be impossible, too.)


Why is perpetual motion impossible?

Perpetual motion is impossible because it violates the laws of thermodynamics, specifically the first and second laws. The first law states that energy cannot be created or destroyed, only transferred or transformed. The second law states that in any energy transfer or transformation, some energy is lost as unusable heat. This means that a perpetual motion machine, which would have to operate without any energy input or losses, cannot exist in reality.


Does a simple machine only has one kind of motion?

No, a simple machine can have multiple types of motion. For example, a lever can have both rotational and linear motion, while a pulley can have rotational motion.


What is a device in which work output equals work input?

A perfectly efficient machine, which doesn't exist in the natural world. The reason it doesn't exist is because any kind of work gives off energy byproducts (for instance, heat differential, friction, so on and so forth). Kind of like a perpetual motion device (which you could make by linking the outputs to the inputs on a perfectly efficient machine).ideal machine


What kind of simple machine is rAke?

A leaf rake is a lever as long as it is in motion


Which other kind of simple machine is a special kind of lever?

A wheel and axle is a special kind of lever, as it combines rotational motion (wheel) with linear motion (lever) to make work easier.

What kind of simple machine is a srew driver?

A screwdriver is a type of wheel and axle simple machine. It consists of a handle (wheel) that rotates and applies force to turn a screw (axle). The threading on the screw converts rotational motion into linear motion.
