Explanation:

Electrical energy is a form of energy resulting from the flow of electric charge. Energy is the ability to do work or apply force to move an object. In the case of electrical energy, the force is electrical attraction or repulsion between charged particles.

Radiant energy is the energy of electromagnetic waves. These waves can travel through space. Electromagnetic radiation is made up of tiny particles called photons – think of them as little packets of energy.

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.

Heat energy is the result of the movement of tiny particles called atoms, molecules, or ions in solids, liquids and gases. Heat energy can be transferred from one object to another. The transfer or flow due to the difference in temperature between the two objects is called heat.

Sound energy is the movement of energy through a substance – such as air or water – in the form of waves. It is produced when a force causes an object or substance to vibrate.
