Across
  1. 1. the transfer of energy when a force causes an object to move in the direction of the force.
  2. 4. energy that is transferred to the surroundings and is not useful for the intended purpose, often as heat or sound.
  3. 6. the internal energy of an object related to the temperature and movement of its particles.
  4. 9. the factor that is deliberately changed in an experiment to observe its effect.
  5. 10. energy that is transferred in a way that helps achieve the intended purpose of a process or device.
  6. 12. a factor that is kept the same during an experiment to ensure that the results are valid.
  7. 13. to spread energy into the surroundings so that it becomes less useful, usually as thermal energy.
Down
  1. 2. the energy an object has because it is moving.
  2. 3. the factor that is measured or observed in an experiment and changes in response to the independent variable.
  3. 5. a statement that suggests what is expected to happen in an investigation, based on prior knowledge or evidence.
  4. 7. observations or measurements collected during an investigation that are used to support or refute a conclusion.
  5. 8. the transfer of thermal energy from a hotter object to a cooler object due to a temperature difference.
  6. 11. a final statement that explains what the results of an investigation show and whether they support the prediction.
