- Law of Conservation of Energy
- Energy cannot be created or destroyed
- Energy can only be transferred or
dissipated
- If an object is thrown or swung, it will not return to the original position as
the starting energy will be transferred and will not have enough energy to
return to the original position, e.g.: A bungee jumper will start with
Gravitational Potential Energy but as they jump, the energy will be
transferred into kinetic energy, and will therefore not return to the original
position.

- Equations
- W = F x d
- Work done = Force x distance
- Work done = Force x distance
- Gravitational Potential
- Ep = m x g x h
- Elastic Potential = mass x gravitational field strength x height
- Elastic Potential = mass x gravitational field strength x height
- Ep = w x h
- Elastic Potential = weight x height
- Elastic Potential = weight x height
- Ep = m x g x h
- Ek = 1/2 x m x (v x v)
- Kinetic Energy = 1/2 x mass x (velocity x velocity)
- Kinetic Energy = 1/2 x mass x (velocity x velocity)
- W = F x d
- Energy Efficiency
- Ee = useful / total
- Asked for in %
- Cannot be more than 100%
- Ee = useful / total
