The rotation and revolution of the earth cannot be counted as a perpetual motion machine, and this movement of the earth, like the motion of all celestial bodies, is propelled by power. The idea of a perpetual motion machine does not exist in this world because it violates the law of conservation of energy. Since ancient times, there have been some whimsical people who want to make such a thing once and for all, but no one has ever succeeded, and some pseudo-successes have been overturned by later experiments.
Originally, this activity should have been stopped after the advent of modern mechanical science, but some people are just elm lumps and tendons, and there is no basis for nonsense.
-
No, the speed of the Earth's rotation and revolution is decreasing year by year due to energy consumption. Moreover, a perpetual motion machine does not mean that once you start, you can keep moving without replenishing energy. A perpetual motion machine is a system that produces more energy than it consumes.
This is the same as keeping the object moving at a uniform speed without any external force.
-
Certainly not, for the sun, the orbiting speed is the earth's rotational speed, which is kilometers and seconds, and the escape speed is kilometers and seconds. If the orbital velocity is less, the earth will move closer to the sun and will eventually be engulfed by the sun; At or above the escape velocity, the Earth will gradually move away from the Sun and eventually away from the Sun. ,
-
The rotation and revolution of the earth do not do external work, so it is not counted, the perpetual motion machine is required to be able to do external work all the time, and the perpetual motion machine refers to the external output power, and it is obvious that it does not stop, which is not considered a perpetual motion machine. That is, it is not considered a first-class, second-class, third-class perpetual motion machine.
-
The concept of a perpetual motion machine is that there is no energy input, and then there is an energy output. There is no energy input for the revolution of the earth, but there is no energy output either, so it is not a perpetual motion machine, it is just inertial motion. These planets have been orbiting the Sun since the beginning of their formation, and since there is no resistance in space, this will continue forever.
-
No, the driving force of celestial motion is in two aspects, one is the original first driving force, which is the big one. The cosmology of the universe believes that the origin of the universe began with a singularity hundreds of millions of years ago, and that space-time appeared only after the singularity of infinitely small, infinitely curvature, infinite density, and infinite heat, and this space-time has been expanding, which is the first driving force; The second is the ubiquitous gravitational pull in the universe, which according to the theory of relativity is curvature.
-
Of course, you can't forget it, what is a perpetual motion machine? A machine that continuously does external work but does not use any energy, does the earth's rotation and revolution do external work? This is the same as the fact that the object maintains a uniform motion without any external force, so the rotation of the earth must not count.
-
Well, let's put it this way, the earth can only be regarded as an accessory of the perpetual motion machine, and the real perpetual motion machine is our boss, the "sun".
-
Certainly not, the long time of movement is not perpetual, and the movement of the earth itself does not do external work.
-
Eternal motion is not possible with the current technology of our human beings. Isn't ignorance equal to ignorance? So how do you deny something you don't know.
Unsuccessful does not mean that you can't succeed, the unknown can only be explored, and the successful person can only be 1 in 10,000.
Think about how the ancients judged our modern civilization, and what reason do we have to go to the future.
The perpetual motion machine is just a concept, while the magnetic motion machine still has the potential to become a reality.
The operation of the planet is the mystery of the universe, and we have not yet armed ourselves to that height, so let's be realistic!

The rotation of the earth is not a perpetual motion machine.
A perpetual motion machine is a machine that does not need to input energy, energy or can continuously move and do work externally under the condition that there is only one heat source. That is to say, there are two conditions that must be met by a perpetual motion machine. One is that there is no external energy input, and the other is that it can continue to do external work, so the rotation of the earth is not a perpetual motion machine.
In fact, for us, the rotation of the earth is mostly a normal state, and it is not a perpetual motion machine.
Generally speaking, the rotation of the earth is a normal state, and it will not stop, but this perpetual motion machine is still to be debated, in some ways, the rotation of the earth is because there is no friction, so it will remain in this state.
The reason why there is no perpetual motion machine on the earth is also because under the action of the earth's gravity, any object will be affected by profit, so it is difficult to guarantee that there will be no loss of energy.
There is no cold air in the gravitational force on the earth, and it is also because of various reasons, the most fundamental is that the movement of any object on the earth requires friction consumption, so it is said that there is no permanent perpetual motion machine.

Who told you that the earth never stops turning? In hundreds of millions or billions of years (or tomorrow), it is unknown whether the earth will still exist, and you say that the rotation of the earth will not stop? People know about any living thing or even an object.
Celestial bodies (including all planets.) Galaxies and even the entire universe) have a lifespan and will perish in the future, you say that the rotation of the earth will not stop? The existence and non-existence of a perpetual motion machine in the established system, many people think that it is a perpetual motion machine without losing energy and want to obtain additional energy to meet their own needs, which is completely impossible.
It is too early to develop a perpetual motion machine, and this is impossible, the rotation speed of the earth is gradually slowing down, in other words, tomorrow is always longer than today, although the amplitude is small, only 1,700 seconds, but what about the accumulation of time? Of course, when you die, you will not see the destruction of the earth or stop the machine, because you have to do external work, there is energy transfer and transformation; The ball is the ball, the earth rotates, and there is no energy conversion. So there is no perpetual motion machine, there is a perpetual motion (ground) ball!
According to the entropy increase theory, the earth will not be in perpetual motion. But don't worry, it won't happen tomorrow. If it is said that as long as it moves, it is a perpetual motion machine, and a glass of water is a perpetual motion machine.
Because the water molecules in it are always moving, and they will not stop. Besides, there is absolutely no anti-bar, it can't be iced, and it is still always moving. The forces of the universe are beyond human control.
When humanity has fully grasped the power of the universe, mankind has entered a remarkable new era. The earth doesn't spin forever, it's slowing down......
The earth is indeed constantly rotating, but this is not perpetual motion, the earth can rotate for about 5 billion years at most, and then it will be destroyed by the sun, or for other reasons, far from forever. The earth is also relying on the gravitational and magnetic forces of itself and the sun, and the law of entropy increase is unsolvable, and one day the earth, the solar system, and even the galaxy and even the universe will die.
-
Because the earth rotates all the time, although no one understands why the ball rotates, there is a reason why the earth has always rotated.
-
This is because of gravity, and there is also a gravitational force between the earth and other planets, so it can rotate all the time.
-
Because there is a gravitational force between the planets, and these forces can keep the earth moving.

If the earth is a perpetual motion machine, then we seem to be able to temporarily classify the earth as a type of perpetual motion machine, because the movement of the earth does not require the input of external energy, but if you carefully deduct the definition, you will find that although the earth is always moving, it does not do external work, which violates the definition of perpetual motion machine, so the earth is not a perpetual motion machine in nature. Ideally, if an object moves in a medium without any resistance, if it has an initial velocity, then it will always remain in its original state of motion, and the magnitude and direction of the velocity will remain the same.
The reason why the perpetual motion machine cannot be manufactured is because of the law of conservation of energy, the external work of the machine will consume energy, and the internal friction of the machine itself will also consume energy. The early perpetual motion machine is to manufacture machinery that does not need energy and continues to output energy, from countless folk experts such as Leonardo da Vinci and other scientists have invested in the development of perpetual motion machine, wasting many people's lifelong energy, but the research of perpetual motion machine finally made people discover the law of conservation of energy, that is, the first law of thermodynamics, as long as the machine does external work, it is natural to continue to input energy, otherwise it can not be sustained. Therefore, there is no perpetual motion machine in the world that can output energy without end.
Why has the Earth been able to keep moving for up to 4.5 billion years? This is because the variable speed of the Earth, i.e., negative acceleration, can also cause asymmetric collisions of space quanta. Since the speed of the Earth's rotation is much smaller than the speed of light, less than 1/10,000, the resulting drag is very small, so the deceleration of the Earth's rotation is also very small, which is negligible relative to the human time scale.
The Earth is not an entity, and there are many tiny particles in space. As a result, there is resistance to the rotation of the earth, which is not eternal, and it will eventually stop rotating. Therefore, the rotation of the earth is not a proof of a perpetual motion machine, but only the result of the conservation of momentum at the time of the formation of the earth.
-
The rotation of the earth is due to the force of the magnetic field, and the non-existence of a perpetual motion machine is due to the absence of an object without friction on the earth.
-
Because the earth has always been subject to gravity, it has always been driven by the outside world, and it does not belong to the perpetual motion machine.
-
Because the reason why the earth can rotate all the time is because it does not encounter enough resistance, and without resistance, everything in the universe will always maintain a constant state of motion. Although the Earth's rotation is gradually slowed down by the gravitational pull of the Sun and the Moon, this effect is so small that we don't feel it at all, and it may not affect the Earth's rotation until the Sun and the Earth are destroyed.

Humans once wanted to use the principle of the earth's motion to make a perpetual motion machine. But it is clear that this idea has been overturned. The Earth revolves around the Sun. This is based on a certain force.
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. >>>More
As the saying goes, the eight kings of a thousand years, the turtle of ten thousand years. So turtles live the longest.
The squirrel is a beautiful little animal, well-behaved, tame, and very likable. Although they sometimes catch birds, they are not carnivores, and often eat almonds, hazelnuts, beeches and acorns. They have delicate faces, sparkling eyes, athletic bodies, light limbs, very agile and alert. >>>More
Yes, it's better to be early**,. It's very uncomfortable.
Wisteria flowers, I have read an article, called Wisteria Garden's Green Mirror Bright Eyes, where the wisteria flowers are also known as memories of the past, it is said that boiling into soup can remind people of the things of the past life, I don't know if it is true.
