Across
- 4. Energy produced when electrons move from one place to another
- 7. Came up with the three laws of motion
- 8. The ability to do work
- 9. A force that opposes motion between two surfaces that are in contact
- 10. the movement of energy through substances; It moves in waves and is produced when a force makes an object to vibrate
- 12. Unequal forces: causes a change in the object's motion
- 15. A type of kinetic energy; energy stored in moving objects
- 16. A push or pull
- 18. A change in speed or direction
- 19. The energy of a moving object
- 20. Also called heat energy; is produced when a rise in temperature causes atoms and molecules to move faster and collide with each other
Down
- 1. The energy stored in an object
- 2. A change in distance or position of an object
- 3. How fast an object moves over a given distance
- 5. A form of electromagnetic radiation; Only energy we are able to see
- 6. Equal forces; does not change an object's motion
- 11. This energy comes from the nucleus of an atom
- 13. The force that pulls objects toward Earth
- 14. An object's speed and direction
- 17. Energy stored in the bonds of chemical compounds
