Across
  1. 1. transfer energy moves from one object to another without changing form
  2. 3. how fast an object is moving
  3. 5. energy Energy obtained after being changed by a process
  4. 8. relationship A relationship between two variables that does not produce a straight line on a graph.
  5. 9. diagram A model that shows how energy is transferred and transformed
  6. 11. energy Energy that is stored and held in readiness
  7. 12. energy energy transferred by light.
  8. 13. efficiency The percentage of energy put into a system that does useful work
  9. 15. a unit for measuring energy.
  10. 18. of conservation of energy the idea that energy can never be created or destroyed, only transferred from one form to another.
  11. 22. potential energy a name used to describe energy when it is stored in stretched or squashed things that can stretch back to their original shape. Another name for 'strain energy'.
  12. 23. potential energy (GPE) energy stored when an object is lifted upwards.
  13. 26. transformation A change from one form of energy to another
Down
  1. 2. energy energy transferred when an electric current flows.
  2. 4. a unit for measuring energy intake or expenditure. 1000 J = 1 kJ
  3. 6. energy energy transferred to where it is wanted in the way that is wanted.
  4. 7. energy a term used to describe energy when it is stored in hot objects. The hotter something is, the more thermal energy it has. Sometimes called 'heat energy'.
  5. 10. energy a term used to describe energy when it is stored in moving things.
  6. 14. A representation of an object or event
  7. 16. energy energy transferred by sound.
  8. 17. energy Energy put into a system or device.
  9. 19. energy energy that is not usefully transferred.
  10. 20. A measure of the amount of matter in an object
  11. 21. energy useful energy + waste energy
  12. 22. something that is needed to make things happen or change.
  13. 24. relationship A relationship that has a straight line graph
  14. 25. potential energy a term used to describe energy when it is stored in chemical substances. Food, fuel and batteries all store chemical energy.
