Text: “Energy”.Energy can be defined as the ability to do work. Physicists classify energy into several types: kinetic, potential, heat, sound, radiant energy (light, for example), and electrical, chemical, and nuclear energy.
Kinetic energy is possessed by a moving object by virtue of its motion. It equals the work done to accelerate the object to a particular velocity; it also equals the work done to bring a moving object to rest..
An object has potential energy by virtue of its position. Two common types are gravitational and elastic potential energy.
An object possesses (обладает) heat, or thermal, energy by virtue of its temperature. It is, in fact, merely a form of kinetic energy, because the temperature of a substance depends on the motion of its component atoms or molecules; the higher its temperature, the faster the molecules move.
Radiant energy consists of electromagnetic radiation and includes radio waves, visible light, ultraviolet and infrared radiation, and X rays. The only form of energy that can exist in the absence of matter, it consists of a wave motion in electric and magnetic fields.
Sound energy consists of moving waves of pressure in a medium such as air, water, or metal. They consist of vibrations in the molecules of the medium.
Matter that has gained or lost some electric charge has electrical energy. The movement of charges constitutes an electric current, which flows between two objects at different potentials when they are joined by a conductor.
Chemical energy is possessed by substances that undergo a chemical reaction, such as combustion. It is stored in the chemical bonds between the atoms that make up the molecules of a substance.
Nuclear energy is produced when the nuclei of atoms change, either by splitting apart or joining together. The splitting process is known as nuclear fission, the joining together as nuclear fusion. Such changes can be accompanied by the release of enormous amounts of energy in the form of heat, light, and radioactivity (the emission of atomic particles or gamma radiation, or both).
The principle of conservation of energy
The total amount of energy, possessed by an object, remains the same. This phenomenon is the principle of conservation of energy, which states, that energy can neither be created nor destroyed, but only converted into other forms.
If mass and energy are considered together, the total amount of mass and energy remains the same. The principle of mass conservation has been modified into what is called the principle of conservation of mass — energy. The Theory of Relativity shows that mass and energy can be considered to be totally interconvertible, and the amount of energy produced, when matter is destroyed, is given by the well — known equation E = mc2 (E is the energy released, m is the mass destroyed, and c is the velocity of light).

Text: Sound Еnergy.Energy may take various forms — sound, chemical, and electrical energy, for example Sound consists of waves of alternate compression and rarefaction that transmit kinetic energy through a medium. If there is no medium, there is no sound; sound waves cannot pass through a vacuum. All sounds originate from vibrating objects, such as the vocal cords in the human throat, the skin of a drum, or the strings of a violin. The vibrations are then passed on through a medium — most commonly air — until they strike the ear drum; the ear converts the vibrations into nerve impulses, which pass to the brain where they are interpreted as sounds. Microphones are the other most common instruments of sound waves into electrical signals.
Waves and sound. There are two types of waves in physics: longitudinal and transverse. Sound waves are of the longitudinal type — that is, their vibrations take place in the same direction as they travel.
Transverse waves are those in which the vibrations occur at right angles to the direction, in which the waves travel — as happens, for example, when a length of rope is moved regularly up and down to give it a wavelike appearance. Ocean waves and light waves also travel by transverse propagation.
Frequency and intensity. The frequency of a sound wave is the number of wavelengths that are completed in a given period of time. The universal unit of measurement is the hertz (Hz), which represents one complete wavelength, or cycle, per second. The human ear is sensitive to sound in the frequency range from about 20 Hz. As people grow older, their ability to perceive high frequencies diminishes.
The intensity of sound is measured in terms of the amount of power that passes each second through a given area perpendicular to the direction of the sound wave. The intensity unit is the decibel (db).
Velocity. Sound can be transmitted by any medium — gas, liquid, or solid — and all sound waves travel at a constant velocity through any given medium at a constant temperature. But depending on their elasticity and density, some mediums transmit waves faster than others.
The velocity of sound is affected by temperature; as the temperature increases, the medium expands. Its density decreases, with the result that the velocity of sound increases.
