Across
- 5. the energy of an object that moves
- 7. energy stored in an object based on the objects position
- 11. a piece of glass that separates white light into colors of the spectrum
- 14. determined by a wave’s amplitude
- 16. potential energy that depends on the height of an object (the higher the object, the more potential energy it has)
- 17. lower pitch
- 18. the energy of electric charges
- 19. something that changes one form of energy to another form of energy (ex. your stomach, engine, phone)
- 21. softer sound because it has less energy
- 22. bending of light, can make an object appear larger or smaller (ex. A straw looks broken in a glass of water)
- 24. potential energy of an object that is stretched or compressed (ex. rubber band, slingshot, spring, bow and arrow)
- 25. heat energy
Down
- 1. higher pitch
- 2. energy caused by an object’s vibrations; carried by sound waves
- 3. the distance from the peak of one wave to the peak of the next
- 4. energy from the sun
- 6. energy an object has when it is in motion
- 8. the bouncing back of a wave when it hits a surface it cannot pass through (ex. Your reflection in a mirror)
- 9. height of a wave
- 10. refract light to help focus and form images of objects (ex. lenses in glasses)
- 12. energy stored in chemical bonds (ex. food, batteries, wood, and gasoline)
- 13. determined by a wave’s wavelength
- 15. the ability to make things happen and is present whenever there are moving objects, sound, light, or heat
- 17. louder sound because it has more energy
- 20. the process of soaking up heat or light (ex. Dark colored clothing absorbs more heat in the sun than lighter colored clothing)
- 23. energy in the form of moving waves of light
