Unit 4 Energy Review

1. the energy of place or position.
4. The energy of an object in motion; it is calculated based on the object's mass and velocity.
6. The total energy of all the particles in a substance; it is related to temperature and can affect the state of matter.
8. the energy in bonds
10. is the transfer of thermal energy between substances due to a difference in temperature
13. the joining together of nuclei
14. Energy from sources that cannot be replenished within a human time frame, such as fossil fuels; these sources are limited and contribute to environmental concerns.
15. the energy that holds the nucleus of an atom together
16. the energy in objects that have a restorative force, such as springs or rubber bands

2. occurs when thermal energy is added or taken away from a system.
3. a law that states energy can't be created or destroyed, but it can change forms
5. is the average kinetic energy of molecules of a substance.
6. Changes in energy from one form to another; such as converting chemical energy in food into mechanical energy for movement.
7. Energy from sources that are naturally replenished, such as sunlight, wind, and water; these sources can help meet societal energy needs sustainably.
9. the splitting of nuclei
11. The capacity to do work or produce change; it exists in various forms such as kinetic, potential, thermal, and more.
12. The stored energy of an object based on its position or condition; for example, a rock at the top of a hill has gravitational potential energy.
