Lets' begin with radiant/light energy. Radiant energy is when electromagnetic energy travels in transverse waves. This energy we see in our everyday lives, such as the sun, and a light bulb such as the one in the slide show. The larger the object releasing the light, the more energy it has. This factor can come into to play with a T.V. screen. For example, with a 30 in. T.V., it will faintly light the room. But with a 70 in. screen it lights up most of the room.
The sun is a form of radiant energy.
Next up is thermal energy. Thermal energy is energy produced by the movement of atoms and molecules in a substance. For example, when we are cold we sometimes rub our hands together. This is an example of thermal energy. It heats our hands. Another example could be a grill, stove, or oven. We've all had close calls with burning ourselves. Or, when wood burns in a fireplace, which creates heat. A way to increase the presence of thermal energy is to make the atoms and molecules go faster.
This burning paper is an example of thermal energy.
The last energy we will talk about is chemical energy. Chemical energy the energy stored in the bonds of atoms and molecules. The mixing of chemicals can cause a reaction, an explosion, steam, substance, and much more. For example, when you mix shaving cream, glue, and liquid starch, it make a stretchy, solid consistency called slime. And when you mix vinegar and baking soda, it make an explosion. Something cool about chemical energy is when it is released it becomes and entirely new substance.
This is an example of chemical energy. The explosive was made with different chemicals.
We also learned about energy transfer. Energy transfer is when one energy turns into another. For example, when you flip a light switch, electrical energy runs through the wires to the light bulb. When the light bulb illuminates the room, it's radiant energy. I believe this is a very interesting concept.
We hope you enjoyed our page and learned more about some of the different kinds of energy.
