Across
  1. 3. A chemical reaction that releases energy as heat and light.
  2. 5. Energy carried by sound waves.
  3. 6. A push or pull that can change an object’s motion.
  4. 7. A unit of power commonly used for engines (1 hp ≈ 746 W).
  5. 10. To change energy from one form to another.
  6. 13. The capacity to do work or cause change.
  7. 14. Energy related to motion, including kinetic and potential energy.
  8. 15. The force applied to move an object.
  9. 17. Energy related to heat and temperature.
  10. 18. To apply force or effort.
  11. 21. The force that attracts objects toward the centre of the Earth.
  12. 24. A unit of energy equal to the work done when a force of one newton moves an object one meter.

Down
  1. 1. The principle that energy cannot be created or destroyed, only transformed or transferred. (12,2,6)
  2. 2. At a 90-degree angle; work cannot be calculated from a force and displacement arranged in this way.
  3. 4. A force that opposes motion between two surfaces.
  4. 8. A unit of power equal to one joule per second.
  5. 9. Stored energy due to position or condition.
  6. 11. A swinging mass demonstrating energy conversion between kinetic and potential energy.
  7. 12. In the work equation, force and distance must be in the same direction. What word describes this?
  8. 16. The force due to gravity on an object, calculated as mass × 9.8 m/s² on Earth.
  9. 19. The movement of energy from one object or system to another.
  10. 20. Describes energy that is lost, often as heat, due to inefficiencies.
  11. 22. The energy of an object due to its motion.
  12. 23. The energy transferred when a force moves an object over a distance (technically displacement).
