Forms of Energy and Examples
The first law of energy conservation states that all the energy in the Universe is constant and as a result, energy can never be created nor destroyed. It can be converted though and that’s what makes most of us enjoy living in the world. The key to a full appreciation of energy is knowing how to access it and how to use it. The first step is knowing its forms.
Light – This kind of energy is otherwise known as solar energy. Anything that can be seen by the naked eye has light. This is because things are visible to us because of color. Color is light. For as long as there is light, there is energy.
Heat – Heat is caused by molecular movement. Heat is a form of energy which we are only able to detect through our tactile senses at a certain temperature. It doesn’t mean that when we feel something which is humanly comprehendible to be cold, there is no heat. Heat is energy.
Sound – Sound is a wave that is caused by the mechanical vibration. Roughly, this is a physical interaction between two objects. This wave is detected at a certain frequency that our ears are sensitive to and that is what gives us the ability to hear.
Kinetic – Kinetic energy is the simplest and most familiar kind of energy. It is any form of energy which shows physical movement.
Chemical – Chemical energy is the kind of energy that is stored within compounds. When chemical compounds rearrange, there is either a loss of energy or a gain of energy. That is why digestion is a chemical process. We digest food and the energy is distributed to all parts of our body and this gives us the sustenance to do work.
Electrical – This form of energy is the kind that is produced as an effect of particles moving through a conductor. These are called electrical charges. The result is electricity which we can use to power our appliances.
Gravitational potential energy – This kind of energy is possessed by anything which is subject to the force of gravity. Therefore, anything that has mass has gravitational potential energy. In the practical world, a ball which is at the edge of a cliff 50 meters high has more GPE than an identical ball on the ground.
Nuclear energy – This is the kind of energy that is found in the nucleus of an atom and it is therefore otherwise known as atomic energy. This energy actually hold the nucleus of an atom together and energy can be a result when nuclei are split apart (fission) or fused (fusion).
