When talking about energy, we must talk about energy conservation. In layman’s terms, it means that the energy of the entire universe is fixed. To put it simply, the same energy is called by different names when attached to different objects. In other words, energy is like a parasite. It must have a place to store it in order to function (unlike parasites, energy It’s a good thing), and the energy placed on humans, animals, plants, microorganisms, etc. is called bioenergy. In the same way, the energy placed on the sun is called solar energy, and the energy placed on the wind is called wind energy. Nuclear energy stored in atoms. . .
To release the energy stored on an object, a process is required. In this way, energy has another way to name it. The energy released through movement is called kinetic energy. Through chemistry The energy released by change is called chemical energy. . . Kinetic energy, chemical energy, etc. are all energies that can be well utilized, and energy that is not well utilized in a certain process is called thermal energy. This thermal energy is not useless, but is scattered in the air. It is absorbed by other random substances, such as snow and rain falling to the ground. It absorbs heat energy and turns into gas, which continues to fall elsewhere, haha!
In addition, the energy emitted by any person or thing must have its source. Suppose we compare the sun to the starting point of energy. When the solar energy reaches the ground, it is absorbed by plants through photosynthesis and becomes bioenergy. When humans and animals eat it, bioenergy is produced. When humans and animals move, in order to complete a certain action, we produce However, during the movement, the excess energy is accidentally released, which is heat energy (in fact, we are releasing heat energy all the time). This heat energy is absorbed by the ground, melts the snow, and turns into water. The water absorbs and turns into steam. The steam releases heat energy and turns into water or snow and falls to the ground, and the cycle starts again, or it is absorbed by plants and becomes bioenergy, and then the cycle starts again. . .
The explanation is rough and not very comprehensive. I don’t know if it can help children. . .
