  Joules / J
• What is the chemical energy store?

  energy that can be transferred through chemical reactions
• What is the kinetic energy store?

  energy stored in a moving object
• what is the thermal energy store?

  energy stored in object hotter than its surroundings
• what is the elastic store?

  energy stored when an object is squashed, twisted or stretched
• what is the gravitational potential energy store? (GPE)

  energy something has due to its height above the ground
• law of conservation of energy

  energy cannot be created or destroyed, it can only be transferred.
• energy transfer:

  • mechanical contact
  • electricity
  • heating
  • chemical reaction
  • waves
