Examples of matter and not

OleMash [197]

Well matter is basically any substance that has mass and takes up space. Example, you have a ball, or a table, or anything really. That is mass. But anything that doesn't take up space or has mass isn't matter. So, anything that doesn't have a mass or take up space is not matter. Hope this helped you understand. :D
