Across
  1. 2. The sum of KE, PE or thermal energy. The total energy cannot change
  2. 4. Stored energy. More height and more mass = More PE
  3. 5. Heat energy
  4. 7. One surface rubbing against the other
  5. 8. Ability to change itself or its environment
Down
  1. 1. Energy cannot be created or destroyed
  2. 3. Moving energy. More mass and speed/velocity = more KE
  3. 6. Anything with mass and takes up space (volume)
