Across
  1. 1. The transfer of heat by the movement of a liquid or gas
  2. 6. energy energy carried by light e.g the sun
  3. 8. the transfer of energy through a substance from one partical to another. heat is transferred through solids and liquids in this way.
  4. 10. of potential energy a ball at the top of a hill
  5. 12. Potential Energy The energy stored in a system of magnets as a result of the exertion of a magnetic force on each other.
  6. 14. of kinetic energy a moving car
  7. 16. energy stored energy
  8. 18. of Conservation of Energy the law that states that energy cannot be created or destroyed but can be changed from one form to another
  9. 19. variable variable that is manipulated
  10. 21. potential energy Energy stored by something that can stretch or compress
  11. 22. energy relates to the displacement of molecules in a space as a function of the normal thermal motions e.g train on train tracks.
  12. 24. energy Energy caused by an object's vibrations e.g speech
  13. 25. energy the energy contained within a system that is responsible for its temperature e.g boiling water on stove.
Down
  1. 2. design A design in which researchers manipulate an independent variable and measure a dependent variable to determine a cause-and-effect relationship
  2. 3. potential energy Energy stored by objects due to their position above Earth's surface.
  3. 4. the transfer of heat through empty space. no substance is needed.
  4. 5. energy energy of motion
  5. 7. for calculation of potential energy Ep=mgh
  6. 8. potential energy Energy stored in chemical bonds
  7. 9. variable what is measured in an experiment
  8. 11. energy the power an atom's charged particals have to casue an action or move an object. e.g lightning
  9. 13. An educated guess
  10. 15. potential energy potential energy that results from conservative Coulomb forces.
  11. 17. potential energy Energy stored in the nucleus of an atom
  12. 20. for energy effciency Efficiency=output x 100 % input
  13. 23. does G equal? 9.8 m/s^2
