Energy
| Question | Answer |
|---|---|
| Energy cannot be created nor destroyed | Law of Conservation of Energy |
| Matter cannot be created nor destroyed | Law of Conservation of Matter |
| Stored energy, like a skateboarder at the top of a ramp | Potential Energy |
| The energy of motion | Kinetic Energy |
| Burning, friction produces | Thermal Energy |
| Vibrations, thunder produces | Sound Energy |
| Batteries, wood, gasoline are all | Chemical Energy |
| Generators produce | Electrical Energy |
| Simple machines and windmills are all | Mechanical Energy |
| Energy is transferred by | conduction, convection, and radiation |
| Energy transferred through direct contact | conduction |
| Energy transferred in currents of liquids and gases | convection |
| Energy transferred by waves through space | radiation |
| These prevent the transfer of energy | insulators |
| These help the transfer of energy | conductors |
| These waves must move through solids, liquids, or gases | mechanical waves |
| These waves can travel through empty space | electromagnetic waves |
| The matter through which a wave travels is called a | medium |
| The top of the wave | crest |
| Trough | the bottom of the wave |
| Wavelength | the distance from the crest of one wave to the crest of the next wave |
| The height of a wave | amplitude |
| How many waves pass a given point in a given amount of time | frequency |
| What determines the color of a light wave? | frequency |
| We can separate sunlight into all different colors using a | prism |
