4.2.3-4.2.4 Review
Across
- 4. Energy produced by vibrating objects that create waves through a medium like air or water.
- 5. Energy of moving electrons.
- 8. The rate at which work is done or energy is transferred. It tells us how quickly something can do work.
- 9. the units used to measure power, equal to one joule of energy used per second.
- 10. The energy an object has due to its motion
- 11. Energy stored in the bonds of atoms and molecules. It is released when those bonds are broken during chemical reactions.
- 12. Heat energy that comes from the movement of atoms and molecules in matter. The faster they move, the more ______ energy is produced.
- 13. The ability to do work or cause change.
Down
- 1. The units used to measure energy or work.
- 2. The law that states that energy cannot be created or destroyed; it can only change forms. The total amount of energy in a closed system always stays the same, though it may move from one object or type to another.
- 3. Energy stored in the nucleus (center) of an atom. It can be released during nuclear reactions, such as fission (splitting atoms) or fusion (joining atoms).
- 5. Energy stored in an object when it is stretched or compressed. It is released when the object returns to its original shape.
- 6. Energy The sum of kinetic and potential energy in an object that is used to do work.
- 7. The energy stored in an object because of its position or condition.
