Why can t a perpetual motion machine be made?

Classmates, there are many manifestations of this energy conversion, the wear and tear of parts consumes energy, and if you repair it, the energy is still consumed and transferred.

But let's think differently! If you want to create a perpetual motion machine, you must find a perpetual motion source, and some perpetual motion principles can be completely established. For example, the magnetic force of a permanent magnet is eternal in a sense, and if we can use this "force", then we can design a perpetual motion machine.

Moreover, I have personally seen a bicycle made by a real perpetual motion machine The details are inconvenient to disclose In a sense, celestial motion can also be regarded as a huge perpetual motion machine.

The so-called perpetual motion machine can be said to change the form of movement of the product without changing the state of the machine.

It can be understood simply from Newton's three laws, the law of inertia, which ensures that the force is not collected in the equilibrium state, his state of motion will not change, and the action force and reaction force ensure that the interaction between the machine and the product is equal, so it is necessary to keep the machine in equilibrium and equal to the interaction with the product, because the form of product motion has changed, so the above two can not be satisfied at the same time.

It is not feasible to manufacture a perpetual motion machine. There are two reasons for him, first, he violated the law of conservation of energy. Second, it violates the second law of thermodynamics. Therefore, it is impossible to make a perpetual motion machine with the current technical method. <>

In junior high school, high school, and even college, the law of conservation of energy is one of the most basic laws of physics we learn. Many motion relationships seem to conform to the law of conservation of energy, but they are not.

In real life, many movements that seem to be conserved in energy are drained from energy. There is a loss of heat energy. The law of conservation of energy is denoted by:

Energy is neither created nor disappeared out of thin air. It is simply a conversion from one form to another, or from one object to another, while the total amount of energy remains the same. However, the heat energy generated when the object is moving cannot be carried by an object, but can only be diffused into the air by the object, which leads to the lack of total energy, so that the conservation of energy cannot be achieved.

The Second Law of ThermodynamicsHe supplemented the first law of thermodynamics, the law of conservation of energy, which states that energy conversion has a direction. But the direction of energy conversion is uncontrollable. According to the British physicist Kelvin, "It is impossible to take heat from a single heat source and convert it completely into useful work without other effects."

This also shows that it is impossible for the internal energy to be converted into mechanical energy without any loss at all. Moreover, when the energy of an object is generated and its direction changes, it all happens to the atoms in the microcosm, which we cannot find in the macrocosm.

When the energy changes directionally, there is no regularity or certainty, it is random, even random. <>

Because of the above situation, the perpetual motion machine cannot be successfully produced on the basis of the current scientific and technological level and the existing physical knowledge.

Not feasible. This is because such a machine is very difficult to manufacture and requires a lot of manpower, material and financial resources, so it cannot be manufactured into a perpetual motion machine.

It is feasible, it may be a problem of cost, or the production principle is not uniform, or it may be a professional problem, so there is no way to make a perpetual motion machine.

It should not be feasible, because it is certainly impossible to build a machine that can always move, after all, our energy is limited, and our parts have a service life.

It is not feasible because after such a machine is built, it will threaten the existence of people and the existence of the universe, and may cause unpredictable dangers.

Perpetual motion machines are not difficult! It seems that if you have money, you can do it! ...

I think in the near future, Perpetual Motion Opportunity will be made.

There is no parallel level of thought to the universe.

The perpetual motion machine cannot be realized because it violates the law of conservation of energy in thermodynamics. The principle of perpetual motion machine is that it does not need to input energy and energy from the outside world, and can continue to do work under the condition of only one heat source, that is, it can operate forever without consuming energy, which does not conform to the principle of energy conservation.

Why can't a perpetual motion machine be realized

According to the law of conservation of energy, energy is neither created nor disappeared out of thin air, but only transferred from one object to another, or from one form to another, and the total amount remains the same.

The laws of thermodynamics are the laws that describe the laws of heat in physics, including the zeroth, first, second, and third laws, in which the idea of a perpetual motion machine violates the first and second laws.

The four basic laws of thermodynamics are considered to be the most rigorous disciplines in the natural sciences, and are the crystallization of hundreds of years of science and technology and experience.

First of all, let's clarify what a perpetual motion machine is: a perpetual motion machine is a machine that does not consume energy and can do work forever. It's not that it's always moving, it's a perpetual motion machine.

Perpetual motion machines are divided into two categories: the first type of perpetual motion machines does not exist, which is an inference based on the law of conservation of energy (the first law of thermodynamics), which is based on the invariance of time translation, and the second type of perpetual motion machines do not exist, which is an inference based on the principle of entropy increase. It is based on the inference of the second law of thermodynamics, that is to say, the "perpetual motion machine is impossible to realize", this slippery proposition is based on the above scientific inferences of the Suila people, as long as the above scientific inferences are overturned, the perpetual motion machine may be invented. "Falsifiability" and "limitations" are both important factors in distinguishing the scientific system from the religious system, science does not claim its absolute correctness and absolute authority, and science acknowledges its "limitations".

So to prove that a perpetual motion machine is possible, you just need to try to overturn the law of conservation of energy, and before you can disprove this scientific evidence, we must first admit that the perpetual motion machine cannot be realized.
