Across
- 2. – stored energy of an object because of its position or shape
- 5. – movement of waves through a substance or object caused by vibrations
- 7. – equal and opposite forces on an object that result in no change in position, direction, or motion
- 9. – management of the use of energy resources
- 10. – natural resources that can be used as a source of energy to do work
- 11. – changing from one form to another (e.g., energy transformation)
- 14. – energy stored in the bonds of atoms and molecules of substances (e.g., food, biomass, petroleum, natural gas, and propane contain stored chemical energy)
- 15. – energy of motion
- 17. – when an object’s speed remains unchanged
- 18. – a form of kinetic energy resulting from the motion of particles that is transferred as heat; associated with the temperature of substances
- 21. (conversion) – process of energy changing from one form to anotherLaw of conservation of energy – states that energy is neither created or destroyed; it only changes form
- 22. – natural resources that can be replaced by nature (e.g., solar, hydropower, wind, biomass)
Down
- 1. – unequal forces on an object that may result in a change in position, direction, or motion
- 3. – the ability to cause change or do work
- 4. – the total distance traveled by an object over a total amount of time
- 6. – stored in objects by force (e.g., stretched rubber band or balloon)
- 8. – movement of electrons (e.g., electrons moving through wires is electricity; lightning)
- 12. – change in an object’s motion (position, direction, speed); caused by unbalanced forces
- 13. – how far an object has moved from its original position; the difference between the final and initial positions
- 16. – natural resources that cannot be replaced once depleted (e.g., oil, coal, natural gas, nuclear)
- 19. movement of objects or substances from one place to another
- 20. – the transfer of energy from a light source (e.g., Sun, fire, light bulb, burner) to an object or substance
