Energy Transfer

3. – A measure of how much a material opposes the flow of electric current.
4. – A complete, closed path through which an electric current can flow.
6. – A machine with blades that are turned by a force like wind, water, or steam to spin a generator.
7. – The transfer of heat or electricity through a substance by direct contact. [Image showing heat transfer via conduction in a metal rod]
11. – A form of energy that can travel through space, including light, X-rays, and microwaves.
13. – The quantity of motion an object has, depending on its mass and velocity.
14. – A material that allows heat or electricity to move through it easily (like copper or aluminum).
15. – An energy source that can be replenished naturally in a short period of time (like sun or wind).
18. – An energy source that exists in limited amounts and cannot be replaced easily (like coal or oil).
19. – A synonym for transformation; the act of changing energy from one state to another.

1. – The energy an object has because it is in motion.
2. – Stored energy that an object has because of its position or condition.
5. – The law stating that energy cannot be created or destroyed, only changed.
7. – Energy stored in the bonds of atoms and molecules (like in food or batteries).
8. – A force that opposes motion between two surfaces that are touching, often creating heat.
9. – The sum of potential and kinetic energy used to do work.
10. – A machine that converts mechanical energy into electrical energy.
12. – The transfer of energy through space by electromagnetic waves, such as light or heat.
16. – A material that does not allow heat or electricity to move through it easily (like rubber or plastic).
17. – The process of changing from one form of energy to another.
