Energy:

• Kinetic energy


  The energy stored in moving objects
• Calculating kinetic energy


  Kinetic energy (in Joules) = 0.5 x mass (in kg) x speed^2 (in m/s)
• The equation for kinetic energy is not given in the exam, so it must be learned
• A car runs on petrol (chemical energy)

  Some of the energy is converted to kinetic energy as the car moves
• Scientists often convert Joules to kilojoules by dividing by 1,000
