10 Types of Energy

Energy is defined as the ability to do work. Energy comes in various forms. Here are 10 common types of energy and examples of them.

Mechanical Energy

Mechanical energy is energy that results from movement or the location of an object. Mechanical energy is the sum of kinetic energy and potential energy.

Thermal Energy

Thermal energy or heat energy reflects the temperature difference between two systems.

Nuclear Energy

Nuclear energy is energy resulting from changes in the atomic nuclei or from nuclear reactions.

Chemical Energy

Chemical energy results from chemical reactions between atoms or molecules. There are different types of chemical energy, such as electrochemical energy and chemiluminescence.

Electromagnetic Energy

Electromagnetic energy (or radiant energy) is energy from light or electromagnetic waves.

Sonic Energy

Sonic energy is the energy of sound waves. Sound waves travel through the air or another medium.

Gravitational Energy

Energy associated with gravity involves the attraction between two objects based on their mass. It can serve as a basis for mechanical energy, such as the potential energy of an object placed on a shelf or the kinetic energy of the Moon in orbit around the Earth.

Kinetic Energy

Kinetic energy is the energy of motion of a body. It ranges from 0 to a positive value.

Potential Energy

Potential energy is the energy of an object’s position.

Ionization Energy

Ionization energy is the form of energy that binds electrons to the nucleus of its atom, ion, or molecule.
