3. Energy the ability to cause change

4. Mechanical Energy Energy of motion AND position (sum of the potential and kinetic energy of an object)

5. Kinetic Energy energy of movement as a result of speed and mass.

6. Energy Transfer the same form of energy being passed from one object to another

7. Energy Transformation energy changing from one form to another form

8. Law of Conservation of Energy Energy cannot be created or destroyed, only transferred or transformed

9. Energy Chain displays the flow of energy through a system

10. Friction A force present when two objects come into contact

11. Thermal Energy The total K.E. of the molecules in a substance

12. Heat The movement of thermal energy from one place to another

13. Temperature the average K.E. of the molecules of a substance.

14. Particle Model Shows the effects on molecules due to the increase or decrease of energy.

15. Conduction heat energy transfer through solids

16. Convection the transfer of heat energy through liquids and gases

17. Radiation the transfer of heat energy through space

18. Wave disturbances that transfer energy without moving matter

19. Frequency The time between two wave crests

20. Amplitude The distance from crest to trough

21. Wavelength The distance between wave crests

22. Mechanical Wave waves that need matter to transfer energy

23. Transverse Wave a wave that travels perpendicular to the disturbance

24. Longitudinal Wave a wave that moves parallel to the disturbance

25. Sound Waves/Sound Energy Mechanical waves that transfer energy to your air and are converted to “noises” in your brain

26. Electromagnetic Wave waves that do not need matter to transfer energy

27. Some Examples of Energy
