        • Everything above ground
      • POTENTIAL
      • ELASTIC
      • Chemical
      • 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
    • Energy and Efficiency
      • Energy is measured in Joules (J)
      • Efficiency=
      • No machine can be more that 100% efficient
