Examples include:

- Light (photons) — electromagnetic radiation. Photons have no rest mass and are not particles of matter though they carry energy and momentum.
- Heat/thermal energy — a form of energy transfer, not a substance.
- Sound — a pressure wave traveling through a medium, not matter itself.
- Fields (electric, magnetic, gravitational) — properties of space that exert forces, not material objects.
- Vacuum (empty space) — absence of matter.

Each of these can interact with matter but are not considered matter themselves.
