Is electrical energy kinetic or potential? Or what is electricity?

First of all, I think we should understand that the electricity in our socket is actually just the transfer of energy, which is the energy transmitted by the distant power plant to the user's home through the grid. It is therefore discussed in two parts. On the one hand, the form of energy in distant power stations, usually kinetic energy (generators can only convert kinetic energy into electrical energy).

Then, the energy conducted inside the wire is transmitted (not by electrons) by a substance called an "electromagnetic field" (yes, it is a substance). This substance is the same substance as the light we see every day, except that the electromagnetic field energy in the wires is much lower than that of light, and it can only move along the wires. The subject thinks that the light is inclined to kinetic energy or potential energy.

Potential energy is the energy contained in the distribution of an object, whereas kinetic energy is the energy contained in the motion of an object. The energy of light is more inclined to kinetic energy (which can be fully counted as kinetic energy processing within the framework of special relativity). The other situation is the electrical energy in the battery, which is an out-and-out potential energy.

The chemical energy of the battery is contained in the molecular structure, which is mainly the arrangement of atomic nuclei and electrons. Noticed. "Arrangement", this energy due to the distribution of matter can be regarded as potential energy.

To sum up, distant power stations usually transmit kinetic energy to users' homes with electric current as a medium. The energy transfer mode of the electric current itself is the same as that of light (both are electromagnetic fields), and it is more inclined to kinetic energy. And the electrical energy in the battery we use in our daily life is an out-and-out potential energy.

Under the heavy stance, the stone walks in a circle according to an arbitrary closed path in space, and the work done is equal to zero. This kind of field is called a conservative field, and the gravitational field is a conservative field, and the elastic force field generated by the spring is also a conservative field. <>

Actually, electrical energy is the energy of an electric field. The orderly movement or accumulation of electric charges is only a manifestation of the energy of the electric field.

Because of the presence of electric field energy, the charge is driven to flow in an orderly manner, so that the charge is concentrated at both ends of the capacitor. But if you just look at this part, it seems that electrical energy is very much like potential energy. But it's a pity that you lift and lower the stone 10,000 times, the height is the same, and the potential energy changes the same every time.

However, if the charge flows in an orderly manner, it will definitely produce a magnetic field, but since it is a charge and discharge, it must be a time-varying electric field, which will definitely lead to electromagnetic field radiation. There must be a part of the energy that continues to leave the charge-discharge circuit. If you do high school exercises, it is often just a charge or discharge, ignoring this part of the loss.

In order to simplify the comprehension of middle school students, we will use the crude concept of "electric potential energy" to explain it. But it also makes students mistakenly think that it is the energy of an electric charge. In addition, the electric field can exist in a vacuum, and the electromagnetic field can propagate completely away from the charge.

Our radio signals, such as satellite communications, travel the energy of the electric field at the speed of light in a vacuum, where there is no electric charge. <>

Potential energy is energy stored in a system that can also be released or converted into other forms of energy. Potential energy is a state quantity, also known as potential energy. Potential energy is not possessed by individual objects but is shared by interacting objects.

Potential energy reflects the strength and magnitude of the interaction between two substances, and the parameters that need to be considered for the magnitude of potential energy are: field strength, position, reference frame, and force. Speaking of the concept of electrical energy, the concept of electrical energy can be used, and you can also look at the textbooks, I am more inclined to think that the general explanation of the concept of electrical energy is to be described as this for ease of understanding.

It refers to the ability to use electricity to do work, in fact, the essence of electrical energy is the energy possessed by the electric field itself, and the electric field is a substance. <>

Electrical energy is electrical energy, which can be converted into kinetic energy. Anything can be converted.

Kinetic energy: The energy that an object has due to its motion, known as the kinetic energy of the object. Its size is defined as one-half of the product of the mass of the object and the square of the velocity.

Potential energy: Potential energy is the energy that belongs to the common energy of the system of things, and it is usually said that the potential energy of an object is actually a shorthand statement. Potential energy is a relative quantity. Choose different potential energy zeros, and the value of potential energy is generally different.

Conversion of kinetic and potential energy.

1. A moving object can do work, and the energy it has due to motion is called kinetic energy; The greater the velocity of the object, the greater the mass of the object, and the greater the kinetic energy of the object.

2. Transformation of kinetic energy and potential energy.

1) Kinetic energy and gravitational potential energy can be converted into each other.

2) Kinetic energy and elastic potential energy can be converted into each other.

3) Gravitational potential energy and elastic potential energy can be converted into each other.

Differences: 1. Kinetic energy is the energy possessed by the motion of an object, which is related to mass, the greater the mass, the greater the kinetic energy; It is also related to velocity, the greater the velocity, the greater the kinetic energy. Everything that moves has kinetic energy.

2. Potential energy is the energy that an object has because it is lifted. It is related to the mass, the greater the mass, the greater the potential energy; It is also related to the height, the greater the height, the greater the potential energy. The potential energy that everything that is lifted up.

Kinetic energy: The energy that an object has due to its motion is called kinetic energy.

The mass and velocity of an object determine the magnitude of its kinetic energy, and the greater the mass and velocity of the moving object, the greater the kinetic energy. And all moving objects have kinetic energy.

Potential energy: Potential energy is further divided into gravitational potential energy and elastic potential energy.

The object is lifted as a result.

And the potential energy possessed is called gravitational potential energy.

Gravitational potential energy refers to the energy that an object has due to being lifted, and all objects that are lifted up are capable of doing work and all have gravitational potential energy. The greater the mass of the object and the higher it is lifted, the greater its gravitational potential energy.

Elastic potential energy refers to the energy possessed by an object due to elastic deformation, and all objects that undergo elastic deformation are able to do work and have elastic potential energy. The greater the elastic deformation of an object that undergoes elastic deformation, the greater the elastic deformation it has.

The formula is: Kinetic potential energy 1 2mv 2
