Gravitational Energy

Gravitational energy is often confused with potential energy. Potential energy is stored in any object, but gravitational energy is only stored in the height of the object. It can simply be described as the kinetic energy or motion caused by gravity. Whenever an object is at a raised point, there is always a force holding it from falling, but if there is no force holding it back it will definitely be pulled down by gravity. An example is a sky diver or a person who dives from a raised point into a pool of water. The force pulling the person down to the ground or into the pool of water is gravitational energy.

8. Radiant Energy

Electromagnetic waves make up radiant energy. It is the form of energy that can move through space such as the sun’s rays or heat. There is no medium transmitting the sun’s energy to earth apart from the electromagnetic waves. In other words, electromagnetic waves are associated with electric and magnetic fields resulting from the acceleration of an electric charge.

A common example is the magnetic force that pulls metals to a magnet. Electromagnetic waves can travel through anything including vacuum, solids or particles. Accordingly, the energy in electromagnetic waves is what is known as radiant energy. The microwave heats/cooks food on the basis of radiant energy.

9. Sound Energy

Sound energy is released from vibrating objects. It may also be considered as the energy through substances in longitudinal (rarefaction/compression) waves. Sound energy is generated when a substance or object is made to vibrate. In precise, it is the wave transferred through a substance or object. For instance, a vibrating guitar transfers energy to the surrounding as sound. The kinetic energy from the moving air transfers the sound to the people’s eardrums. Sound energy is measured in pascals and decibels.
