Across
- 2. a type of energy that comes from charged particles, like electrons moving through a wire
- 6. the energy that is stored in matter and that can be released by a chemical reaction
- 7. to bounce light, heat or sound waves from a surface without absorbing them.
- 9. to move steadily back and forth with continuous quick, shaking movements; particles do this as they pass through matter (solids, liquids, gases) to create sound.
- 10. bend,the ability for light to change direction when it hits certain objects
Down
- 1. the power that an object gets from its position and motion; the ability to do work
- 3. a material that does not allow heat to move through it easily; it reduces or prevents the transfer of electricity, heat, or sound; gases are good insulators
- 4. to soak up or take in energy without reflecting or transmitting that energy
- 5. a material that allows heat to move through it easily; solids are good conductors.
- 8. the relative frequency of a sound; how high (particles vibrate faster) or low (particles vibrate slower) a sound is
