- Energy can be tranferred from on form to another
- Conservation of energy
- Cannot destroy energy
- Conservation of energy: total amount of energy is always the same.
- Useful energy
- energy we want.
- Wasted energy isn't useful
- Useful and wasted energy end up being transferred to the surroundings, making it warmer
