Matter is anything that has mass and energy and occupies space by having volume.

  • Matter describes the physical things around us – earth, air and any object that can be named.
  • Matter is made up of particles – atoms and molecules.
  • Subatomic and atomic particles have mass and energy.
  • Light is a form of energy, not matter.
  • Einstein’s equation E=MC2 suggests that anything having mass has an equivalent amount of energy and vice versa.
