Energy is a physical quantity.It implies a diversity of movements of natural substances.Different forms of matter correspond to different forms of energy.
In everyday reality, most often seen direct movement and interaction of physical substances and their parts.Thus there is a selection of mechanical energy.She is known to mankind since ancient years.The most common sources are its wind and river current, tides, animals and people.Types of mechanical energy type are divided into two groups.These include kinetic form which have a body in motion, and the potential that is contained in the resting matter.
variety of forms of energy that exist in nature include the shape and light.It is known to all, and each is accompanied throughout its life span.Types of energy sources of light are known from ancient times.It is the sun and the moon, the stars, bonfires and torches, as well as the plants and animals of certain chemiluminescent families.All living beings on this planet can exist only through the power of light.Its main source of the world has been and remains the sun.None of this star, our planet would look like the lifeless body, dressed in a huge thick ice shell.Rays sent heavenly body, are able to accumulate and to other forms of energy.Thus, warming atmosphere and the Earth's surface, the Sun is the source of heat.This kind of energy is the root cause of occurrence of wind.In turn, this natural phenomenon a source of mechanical motion.Thanks to sunlight occurs energy gas, oil and coal deposits, as well as forests, fields and meadows, called chemical.
has enormous power and the movement of water particles.The wave energy is a constant transition from the kinetic to the potential form.Each of these movements is able to transmit with his characteristic speed.The primary source that feeds the energy of waves, in most cases, is the wind, which arises as a result of heating of the earth's surface.
In nature, there is also the movement of sound waves.The energy transferred alternately compressible layers and discharged air travels through space at the speed of sound.The movement of the waves of electromagnetic fields in physics is called radiation.This type of energy is transferred similarly sound and water.Its main sources are cosmic radiation, magnetic field of our planet, as well as certain types of fish.
When it comes to energy use, it is classified on the free (mechanical and electrical, chemical and electromagnetic and nuclear) and chaotic (thermal).All types of movement do not arise out of nothing, and do not go unnoticed.The free forms of energy moving in a chaotic, having a lower temperature, and can be used almost completely.
In today's world of humanity applies not only due to natural phenomena.It learned to distinguish it from other forms: chemical, mechanical and electromagnetic.
primary source of any of the types of energy are thermonuclear reactions taking place on the sun.In this connection, the scientists of the world have set themselves the task, the solution of which will receive artificial light.New forms of energy need to give impetus to the rapid development of agriculture and industry.If humanity is to have inexhaustible reserves of thermonuclear power, it is able to carry out any of their dreams.
