The Presence of Energy is all Around Us

Energy is everywhere. If you’ve ever taken physics, you know that all matter is composed of energy and it’s all been around for a very long time. If something is moving, it contains energy and from that movement, we can acquire thermal or heat energy. By speeding something up, heat is eventually produced, hence the term, heat energy.

Chemical Energy

When parts of a single compound or molecule are combined with that of another, chemical energy is produced. The movement of a compound through a series of processes, such as the human body and the digestive process gathers energy and eventually lends itself to our bodies and the energy they use. This energy heats and fuels the body and hence you have heat energy.

Electricity

Electricity itself is not naturally heat energy. It is a fast moving current of energy that actually occurs naturally. However, in the manner in which we use electricity and create electricity, it is very much a form of heat energy. By connecting an electrical current to a conductor, usually a metal that excites the electrical charge, electricity is sped up, creating heat through the enhanced movement of the molecules involved.

Mechanical Energy

Mechanical energy is the energy resultant from the movement of a physical object in motion, the easiest form of heat energy to both see and explain because it happens on a very physical level. For example, when a piece of machinery operates, turning at a high speed, it creates heat naturally. The fan belts on an engine or the pistons in that engine for example all turn rapidly and require both the air from outside and the coolant in the radiator to keep from overheating.

Solar Energy

Solar energy is the term used to describe all energy harvested from the sun’s rays, having traveled 93 million miles to both warm us and give us light. As the light arrives from the sun, heat is transferred to the earth, heating the surface and atmosphere, keeping the temperature of the planet at a level at which living things can survive.

Friction

This is the most common form of energy, seen in nearly every aspect of our daily lives. If you rub one object against another, heat is formed. It’s that simple. Friction is what causes things to stop moving, such as the disc brakes on your car, which will eventually wear down from the heat energy transferred through the metal. Heat energy transfers when you rub two sticks together to start a fire, or rub flint against stone. On a very basic level, this is energy transfer at its simplest.
