Energy

4. unit used to express energy
5. a measure of how hot or cold something is; a measure of the average kinetic energy of the particles in an object
6. a material that allows heat to flow easily through it
9. a force that opposes motion between two surfaces that are in contact
10. heat transfer through direct contact of molecules
11. energy of a compound that changes as its atoms are rearranged (reacts)
14. the capacity to do work
15. The energy of moving electrons
17. states that energy cannot be created or destroyed but can be changed from one form to another
19. a change from one form of energy to another
20. heat transfer through empty space, in the form of electromagnetic waves

1. form of mechanical energy, stored energkineticenergy form of mechanical energy that moves
2. the amount of work an object can do because of the object’s kinetic and potential energies
3. energy something has due to its height or weight
6. Kinetic energy of a substance’s particles, More movement, more heat
7. Produced by the vibrations of electrically charged particles thru electromagnetic waves. can travel through matter or a vacuum
8. Caused by an object’s vibrations. A vibrating object transmits energy through waves in air around it
12. energy that comes from changes in the nucleus of an atom (either splits atoms(fission) or fuses them (fusion)
13. movement of heat by transfer of energy from one object to another
16. the energy transferred between objects that are at different temperatures
18. heat transfer by movement of a fluid like air or liquid
