  1. Matter and energy are different in classical physics terms. Matter is your computer, your desk, the air you breathe - anything that has mass and takes up space. It comes in three states: gas, solid, liquid. (Some add plasma as a state to account for a gas that has been highly ionized.) Energy, on the other hand, is the ability to make matter take action. However, the modern understanding of mass and energy is that they are same. Mass is just how much energy something contains.
