Hi, I know this is a bit of an easy question, but I'm having a hard time distinguishing between energy and matter.

Can you help me?

    Hi Quiet Dragon!

    • Energy is defined as "the ability to produce a change or perform work involving movement, heat or light ”.

    • Matter is defined as “a substance that makes up everything around us”.

    In short, matter has an extent. We can touch it, perceive it, etc. Energy can affect matter, for example, when heating (thermal energy) water (matter).

    The unit of energy is the joule (J) while matter can be measured by its different properties: mass, quantity, volume, etc.

    There are four types of energy: thermal energy, chemical energy, kinetic energy, and radiant energy. Matter exists in three phases: solid, liquid and gas.

    Do not hesitate if you have other questions!
