Knowledge Bank Energy Types of Energy. In a Flash Light is a form of radiant energy. Forms of energy There are many different types of energy, which all fall into two primary forms — kinetic and potential. What are the different types of energy? Discover the different types of energy. Thermal Heat Energy Thermal energy is created from the vibration of atoms and molecules within substances. Let's go! Chemical Energy Chemical energy is stored in the bonds of atoms and molecules — it is the energy that holds these particles together.
Nuclear Energy Nuclear energy is stored in the nucleus of atoms. Electrical Energy Electrical energy is the movement of electrons the tiny particles that makeup atoms, along with protons and neutrons.
Radiant Energy Also known as light energy or electromagnetic energy, radiant energy is a type of kinetic energy that travels in waves. Light Energy Light energy is a form of electromagnetic radiation.
Motion Energy Motion energy — or mechanical energy — is the energy stored in objects; as objects move faster, more energy is stored. Sound Energy Sound energy is the movement of energy through substances. Elastic Energy Elastic energy is a form of potential energy that is stored in an elastic object - such as a coiled spring or a stretched elastic band. Gravitational Energy Gravitational energy is a form of potential energy. What is the Law of Conservation of Energy? Kinetic energy is the energy of a moving object.
Potential energy is energy that is stored in an object or substance. Energy Transformations see diagram… Notice that these energy transfer examples only show the useful energy transfers. Cool Facts The word energy comes from the Greek word 'energeia', meaning 'activity. Cool Facts The use of the word 'energy' dates all the way back to the 4th century BC.

This form of energy is called potential energy because it is possible for that object to do work in a given state. Objects transfer their energy between potential and kinetic states. Once the ball is released, its kinetic energy increases as the ball picks up speed.
At the same time, the ball loses potential energy as it nears the ground. Other examples of potential energy include the energy of water held behind a dam or a person about to skydive out of an airplane. Potential energy is not only associated with the location of matter, but also with the structure of matter. A spring on the ground has potential energy if it is compressed, as does a rubber band that is pulled taut.
The same principle applies to molecules. On a chemical level, the bonds that hold the atoms of molecules together have potential energy. This type of potential energy is called chemical energy, and like all potential energy, it can be used to do work.
For example, chemical energy is contained in the gasoline molecules that are used to power cars. When gas ignites in the engine, the bonds within its molecules are broken, and the energy released is used to drive the pistons. The potential energy stored within chemical bonds can be harnessed to perform work for biological processes.
