  1. 2. Formula for kinetic energy (use symbols: 1/2 for half, M for mass, V for velocity; write as ½MV² with no spaces)
  2. 4. Both kinetic and potential are forms of this type of energy
  3. 5. Systems with potential energy can exert forces and produce this form of energy as they change
  4. 9. The S.I. unit of energy (or work)
  5. 10. Common examples of changes that show energy: temperature, pressure, or this (for potential) / this (for kinetic) – use the one-word term that fits best as "position" here
  6. 12. The energy an object has because of its position; it can convert to kinetic (two words)
  7. 13. Energy of motion (two words)

  1. 1. Pushing with 1 N over 1 m on a 1 kg object uses exactly one of these
  2. 3. Energy possessed due to motion or position (two words)
  3. 6. Potential energy is energy due to this (the main factor in gravitational PE)
  4. 7. Kinetic energy depends on mass and this squared quantity (from the formula)
  5. 8. Energy measures the ability to cause this in other things (or in themselves)
  6. 11. Formula for potential energy (three characters, no spaces: use M for mass, G for gravity, H for height)
