- - - - Work done
        
        Measure of how much energy is transferred mechanically
        
        Work done (J)= Force (N) x distance moved parallel to force (M)
        
        W = Fs
        
        Power
        
        The rate at which work is done
        
        Power = Work done/Time
        
        P = e/t = w/t
  - - - Ek = mv^2/2
      - Kinetic energy = 1/2 x mass x speed^2
    - - Ee = 1/2 x k x e^2
      - Elastic potential energy = 1/2 x spring constant x extension ^2
      - Hooke's law states that the extension of a spring is directly proportional to the force applied providing that the limit of proportionality is not exceeded
        
        An object is elastically deformed if it returns to its original length and shape when the force is removed
        
        An object is inelastically deformed if it does not return to its original legnth even when the force is removed
    - - Ep = mgh
      - Gravitational energy potential = mass x gravitational thingy x height
  - - - Indication of how much of the energy supplied is used as an useful output
      - Efficiency = useful output energy transfer/total input energy transfer
      - Or Efficiency = useful power output/total power input
- - - - Local habitats are affected by the large areas that need to be flooded to build dams
    - - Low
    - - Takes up space
    - - Very low
    - - Blocks sewage
    - - Very little
    - - Carbon neutral
- - - - Velocity
        
        V = Displacement/Time
      - Displacement
      - Acceleration
        
        Acceleration = Change in velocity/Change in time
  - - - Speed
        
        S = DIstance/Time
      - Distance
