The moon, the moon, the moon in the apocalypse is produced from the underground world according to Fan Bin. The moon in the apocalypse plays a very important role in this world. Lin Feng discovered that the energy component of the moon is particles that can store energy and reflect energy. After the matter was formed, Lin Feng knew that there might be other secrets in this world, and these secrets could help Lin Feng enhance his own energy.
Energy is a measure of the degree to which the spatiotemporal distribution of mass may change, and is used to characterize the ability of a physical system to do work. It has been proven both in the apocalypse and in the original world that there is a mutual transformation relationship between matter and energy.
Energy exists in many different forms; according to the different forms of movement of matter, energy can be divided into mechanical energy, chemical energy, thermal energy, electrical energy, radiation energy, nuclear energy, light energy, tidal energy, etc. These different forms of energy can be converted into each other through physical effects or chemical reactions. Various fields also have energy.
Corresponding to the various forms of motion of matter, energy also has various forms, and they can be converted into each other in certain ways.
In thermal phenomena, it is manifested as the internal energy of the system, which is the sum of the kinetic energy of the irregular movement of the molecules in the system, the potential energy of the interaction between molecules, and the energy within the atoms and atomic nuclei, but does not include the mechanical energy of the overall movement of the system.
The spatial attribute is the extension of the movement of matter; the time attribute is the persistence of the movement of matter; the gravitational attribute is the reflection of the interaction caused by uneven mass distribution during the movement of matter; the electromagnetic attribute is the movement and change process of charged particles. external manifestations in , etc. There are various forms of movement of matter, and each specific form of material movement has a corresponding form of energy.
The energy form corresponding to the mechanical movement of macroscopic objects is kinetic energy; the energy form corresponding to the molecular movement is thermal energy; the energy form corresponding to the atomic movement is chemical energy; the energy form corresponding to the directional movement of charged particles is electrical energy; the energy form corresponding to the photon movement is Light energy, etc. In addition to these, there are also wind energy, tidal energy, etc. When the form of motion is the same, the motion characteristics of the object can be described by certain physical or chemical quantities. The mechanical motion of an object can be described by physical quantities such as speed, acceleration, and momentum; current can be described by physical quantities such as current intensity, voltage, and power. However, if the forms of motion are different, the only physical quantity that can describe and compare the motion characteristics of matter with each other is energy. Energy is the common characteristic of all moving matter.
Energy can be stored in a system without taking the form of matter, kinetic energy, or electromagnetic energy. When a particle moves a certain distance in a field with which it interacts (by an external force), the energy required to move the particle to a new position in the field is stored. Of course, the particle must maintain its new position through an external force, otherwise the field it is in will push or pull the particle back to its original state. This energy stored by particles changing positions in a force field is called potential energy. A simple example is that the work required to lift an object upward in a gravitational field to a certain height is potential energy (potential energy).
Any form of energy can be converted into another form. For example, potential energy can be converted into kinetic energy when an object moves freely to different positions in a force field. When energy is in a non-thermal form, its conversion into other types of energy can be very efficient or even perfect, including electricity or the production of new matter particles. However, if it is thermal energy, when it is converted into another form, as described by the second law of thermodynamics, there will always be a limit to the conversion efficiency.
In all energy conversion processes, the total energy remains unchanged because the energy of the total system is transferred between systems. When energy is lost from one system, another system must receive the lost energy. , leading to a balance between loss and gain, so the total energy does not change.
Although the total energy of a system does not change over time, the value of its energy may vary depending on the frame of reference. For example, a passenger sitting in an airplane has zero kinetic energy relative to the airplane; but relative to the earth, the kinetic energy is not zero, and it cannot be compared with the earth in terms of individual momentum.
According to the kinetic energy theorem, if a moving object is hindered and slows down until it stops, the object will do work on the obstacle. The amount of work done is equal to the amount of original kinetic energy of the object. Therefore, it can be said that kinetic energy is the ability of an object to do work due to motion. For example, a bullet flying at high speed has kinetic energy, so when it hits the steel plate, it can do work on the steel wrench and penetrate it; a hammer hitting the forging has kinetic energy, so it can do work on the forging and deform it.
The energy released or absorbed when a substance undergoes a chemical change (chemical reaction). Its essence is the change of the outer electrons of the atom, resulting in the change of the electron binding energy and the release of energy. The annihilation of electron-positron pairs into photons is the conversion of the static energy of electrons into the energy of photons.
The kinetic energy of thermal motion of atoms and molecules within a substance. The higher the temperature, the greater the thermal energy contained in the substance. A heat engine is where the expanding water vapor turns its thermal energy into kinetic energy.
The binding energy of the nuclei in the nucleus, which can be released into the kinetic energy of the reaction products during nuclear fission or fusion reactions. Therefore, an object also has energy when it is at rest. The energy and quality of matter are closely related. The mass of the nucleus is smaller than the total mass of the nucleons that make up it. That is, energy is released when free nucleons combine to form a nucleus. This energy is called the binding energy of the nucleus. Heavy nuclei with a lower specific binding energy (the average binding energy per nucleon in the nucleus) fission into lighter nuclei with a higher specific binding energy, or several light nuclei with a lower specific binding energy aggregate into a heavier nucleus with a higher specific binding energy , the energy released is atomic energy.
People have confirmed the law of conservation of energy based on a large number of experiments, that is, when different forms of energy are converted into each other, their magnitude is conserved. The Joule thermal work equivalent experiment is a famous experiment that confirmed the law of energy conservation in the early days, and then established the first law of thermodynamics of energy conversion and conservation in the macroscopic field. The Compton effect confirmed that the law of conservation of energy is still correct in the microscopic world, and later gradually realized that the law of conservation of energy is determined by time translation invariance, thus making it a universal law in physics (see symmetry and conservation law). In a closed mechanical system, if there is no conversion between mechanical energy and other forms of energy, mechanical energy is conserved. The law of conservation of mechanical energy is a special case of the law of conservation of energy.
