| Question | Answer |
|---|---|
| the bending of light as it passes from one material to another | refraction |
| when light bounces back after striking an object | reflection |
| objects let all light pass through them so objects on the other side can be seen clearly | transparent |
| do not let any light pass through them | opaque |
| objects let some light through, but not all light | translucent |
| lenses refract light and make objects look larger | convex |
| lenses refract light and make objects look smaller | concave |
| does not allow thermal energy to pass through them easily | insulators |
| allow thermal energy to pass through them easily | conductor |
| energy that is stored in an object, not in motion, but capable of moving, a parked car on hill, a coiled spring, charged battery | potential energy |
| energy possessed by a body because of its motion, car going down a hill, bowling ball striking pins | kinetic energy |
| energy of motion | mechanical |
| also known as heat energy | thermal energy |
| energy produced when an object vibrates | sound energy |
| you hear because what vibrates | eardrum |
| travels in a straight line | light |
| the average speed of particles in a substance, measured in Celsius or farenheit | temperature |
| form of energy that travels in waves and can move through empty space where there is no air | light energy |
