Sound, mechanical motion, heat, and light are not easily classified as kinetic and potential energy. They are evidence of energy. Movement , sound , heat , and light provide evidence that energy is present and being used.
Sound is produced when we strike something. But does sound do work? Yes, sound can move things. Sound waves move the tiny bones in your ear and shake windows when a loud truck passes by. Sound waves are also evident in the vibrations from playing a radio. Our body is working even when it appears to be still. Breathing, blinking, and digesting food all require energy. For us to do these activities, our bodies burn the energy in food.
We know this is happening because we feel warm burning generates thermal energy [heat]. Therefore, heat is evidence that energy is being used. Light is an example of electromagnetic radiation and has no mass, so it has neither kinetic nor potential energy.
The remaining forms have qualities of both kinetic and potential energy. Sound is made up of vibrations put your hand on a stereo speaker , thermal energy consists of moving molecules in air or in an object, and mechanical energy is the combination of kinetic and potential energy of a moving object. A pendulum has mechanical energy; it continually converts kinetic energy into gravitational potential energy and back into kinetic energy as it swings back and forth. Light is another observable form of energy.

This energy is released when the nuclei are combined fusion or split apart fission. Nuclear power plants split the nuclei of uranium atoms to produce electricity.
Electrical energy is the movement of electrons the tiny particles that makeup atoms, along with protons and neutrons. Electrons that move through a wire are called electricity. Lightning is another example of electrical energy.
Also known as light energy or electromagnetic energy, radiant energy is a type of kinetic energy that travels in waves. Examples include the energy from the sun, x-rays, and radio waves. Light energy is a form of electromagnetic radiation. Light consists of photons, which are produced when an object's atoms heat up. Light travels in waves and is the only form of energy visible to the human eye.
Motion energy — or mechanical energy — is the energy stored in objects; as objects move faster, more energy is stored. Examples of motion energy include wind, a flowing river, a moving car, or a person running. Sound energy is the movement of energy through substances. It moves in waves and is produced when a force makes an object or substance vibrate. There is usually much less energy in sound than in other forms of 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. Elastic objects store elastic energy when a force causes them to be stretched or squashed. A book sitting on a table has potential energy. Thermal energy or heat energy reflects the temperature difference between two systems. Example: A cup of hot coffee has thermal energy.
You generate heat and have thermal energy with respect to your environment. Nuclear energy is energy resulting from changes in the atomic nuclei or from nuclear reactions. Example: Nuclear fission , nuclear fusion, and nuclear decay are examples of nuclear energy.
An atomic detonation or power from a nuclear plant are specific examples of this type of energy. Chemical energy results from chemical reactions between atoms or molecules. There are different types of chemical energy , such as electrochemical energy and chemiluminescence. Example: A good example of chemical energy is an electrochemical cell or battery. Electromagnetic energy or radiant energy is energy from light or electromagnetic waves.
Example: Any form of light has electromagnetic energy , including parts of the spectrum we can't see. Radio, gamma rays , x-rays, microwaves, and ultraviolet light are some examples of electromagnetic energy.
Sonic energy is the energy of sound waves. Sound waves travel through the air or another medium. Example : A sonic boom, a song played on a stereo, your voice. 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.
