Energy

7. heat transfer through particle movement can happen through empty space; it doesn't need gas or fluid.
9. tiny charged particles moving through a conductor or circuit.
10. What kind of energy that is stored in objects by tension.
11. the ability to do work or make things happen.
12. a material that doesn't allow the transfer of energy easily (electrical or heat)

1. transfer of energy (usually heat energy) through direct contact.
2. Energy that is stored in the molecules and matter of substances.
3. potential energy stored in an object's height. The higher the object, the higher its potential ____ energy.
4. Stored energy.
5. heat transferred through a fluid or a gas like water of air.
6. Energy something has when it is moving
8. Energy measured by temperature. Also called heat energy, this energy can be transferred through condustion, convection, and radiation.
13. A kind of energy that moves in waves THROUGH matter as vibrations. We can hear it.
14. this type of energy travels in waves and can be seen as colours.
