Hello, Learners! This is EarthPen. Today, we are going to talk about another fun topic in Physics. It is all about the types of energy.

Energy can be categorized into two broad topics; kinetic energy and potential energy. These two are the basic forms of energy. And we know that kinetic energy is the energy of moving objects while potential energy is energy that is stored. But aside from these two energies, there are also other types of energy. This includes thermal energy, radiant energy, light energy, chemical energy, nuclear energy, electrical energy, gravitational energy, and mechanical energy.
Let us discuss them one by one.

The first type of energy that we’re going to discuss is thermal energy. Thermal energy or also called heat energy is produced when there is a rise in temperature that causes atoms and molecules to move faster and collide with each other.
But how is thermal energy produced? Thermal energy is the energy that comes from the heated up substance which means that the hotter the substance, the more its particles move, and the higher its thermal energy.

To better understand this, let us have an example. Say you have a hot pot. You forgot that the pot is hot so you grabbed it with your hand. Now, your hand is burnt because of the hot pot. The thermal energy from the hot pot is being transferred to your hand that is why you felt the burn in your hands. So, better be careful when dealing with hot things.

The next type of energy that we’re going to discuss is radiant energy.
What is radiant energy? Radiant energy is a form of electromagnetic energy. This type of energy can take the form of visible waves, which is what we call light energy. But we’ll be talking about light energy later.

The sun produces a lot of radiant energy which is transmitted to Earth as light. Radiant energy that is transmitted by electromagnetic waves can come in different forms. Some examples of radiant energy are from the sunshine, xrays, and radiant heating systems.
