This kind of energy is known as ‘potential energy’ as it can be stored until it’s released - usually giving way to kinetic energy! Even lightbulbs when they’ve been on for a long time - ouch!Įlastic - Stretch a rubber band, or pull back the elastic on a slingshot and you’ll have elastic energy. Thermal - If you’ve ever worn thermal underwear you might guess that thermal energy is about heat! The sun gives off thermal energy, as do radiators and fires. So do the brakes on our bikes when we’re traveling fast. Apart from our voices there are plenty of other examples of sound energies - guitars have sound energy when plucked using kinetic energy. Sound - The louder we shout the more sound energy we are using. Plants convert light energy into chemical energy (food) which helps them to grown, this is known as photosynthesis. ![]() Examples of things that have radiant energy are the Sun, lightbulbs and our computer screens. To run, cycle, climb and move the mouse for a computer we use kinetic energy. Kinetic - Anything that moves has this kind of energy. The following chapters describe the various forms energy can take and the story behind humans, energy, fuel and the environment.įirst let’s take a look at the different forms energy can take and how they can be converted. Here’s a great video by scientists showing the many ways that energy can be transferred and converted. For example, the chemical energy we get from our food turns into kinetic and thermal energy (see below) when we walk and sound energy when we shout. ![]() ![]() We use it every day, we have it in our bodies and some of it comes from other planets! Energy can never be made or destroyed, but its form can be converted and changed. Energy is invisible yet it’s all around us and throughout the universe.
