Energy Vocabulary
Physical Science Grade Five/Energy Vocabulary
| Question | Answer |
|---|---|
| The type of energy that is produced by the vibration of matter | Sound energy |
| The type of energy that requires a medium to travel through. It cannot travel through space. | Sound |
| The highness or lowness of a sound. | Pitch |
| This is the number of sound waves that pass by in a time period (usually per second). It determines the pitch of a sound. | Frequency. |
| The loudness/softness of a sound. Also referred to as the amplitude. | Volume. |
| The larger an object, the _________________ the pitch. (lower, higher) | lower |
| The thinner a guitar string is, the _______________the pitch will be. (lower, higher) | higher. |
| When light waves travel from air into water or a different transparent material, it bends. This is called _________________. | refraction |
| This transparent object, usually made of clear glass or plastic, bends white light and separates it into the colors of the rainbow. | a prism |
| A material that lets nearly all light through it. | Transparent |
| A material that lets some light through, but not all. | translucent |
| A material that blocks light. | opaque. |
| A black object ___________________ all light. (absorbs/reflects) | absorbs |
| A white object ______________________ all light. (reflects/absorbs) | reflects |
| A shadow occurs because an object does this to light. | blocks |
| Another name for a mirror image, or light that bounces back. | Reflection. |
| What does ROYGBIV stand for? | the colors of visible light (Red, orange, yellow, green, blue, violet, indigo and violet) |
| The only part of the electromagnetic spectrum that we can see with our eyes. | The visible spectrum. |
| Mechanical energy that is moving is this type of energy. | kinetic. |
| Mechanical energy that is stored is called this type of energy. | potential. |
| Name the two factors that affect the kinetic energy of an object. | the mass and speed of the object |
| Which has more potential energy, a boy at the top of a small hill or a boy at the top of a mountain? | on the mountain (the higher up you are, the greater the potential energy) |
| Name the three metals that a magnet will attract to. | Iron, cobalt and nickel. Remember: steel contains iron, and therefore is attracted to a magnet. |
| Name the two ways to increase the strength of an electromagnet. | 1. Increase the number of wire coils wrapped around the magnet. 2. Increase the power (add batteries or electricity). |
| What will happen if I place two like poles of a magnet together (N-N or S-S)? | They will repel, or push away |
| How can you get two magnets to ATTRACT to one another? | Put opposite poles together (N-S) |
| Coins are attracted to a magnet. (True/False) | False. Coins do not contain iron, silver or nickel (not even nickels!) |
| Gold and silver are magnetic. (true/false) | False. |
| Where are most electromagnets found? | In electric motors. Remember: you cannot have an ELECTROmagnet without ELECTRICITY! |
| The ability to do work or cause change. | energy |
| The transfer of heat energy through space/air. | Radiation (think sun's rays or toasting a marshmallow over a fire) |
| The transfer of heat energy through touching objects/materials. | Conduction (think of a spoon sitting in a cup of hot cocoa; it will get hot also) |
| The transfer of heat energy through moving currents of hot air or hot water. | Convection. (think of hot air rising, cooling and falling, and heating again like an hot water filled radiator) |
| A material that allows energy to easily pass through it, such as electricity or heat. | A conductor. |
| A material that does not allow energy to pass through it easily (such as rubber or glass) | An insulator. |
