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.
