Forces
| Question | Answer |
|---|---|
| Charge of electrons | negative |
| Charge of protons | positive |
| Charge of neutrons | Neutral (no charge) |
| How do motors convert energy? | From electrical to mechanical |
| How do generators convert energy? | From mechanical to electrical |
| What is transferred during conduction? | Electrons |
| What is the sudden flow of electrons between objects? | Static discharge |
| conduction | Two objects with a different charge touch, and electrons are transferred. |
| induction | An electrically charged object is brought near a neutral object. Parts of the neutral object become charged with static electricity. |
| friction | Electrons are transferred when two neutral objects are rubbed together. |
| conductor | Material that allows electrically charged particles to easily flow through it |
| insulator | Material that does not allow electrically charged particles to easily flow through it |
| Things that make electromagnets stronger | More wire turns, greater voltage, adding dry cells, increasing the size of the iron core, lowering the temperature |
| What most affects friction? | The textures of the object and the surface |
| What two things affect gravitational force? | Mass (greater mass = greater force) and distance (less distance between objects = greater force) |
| Mass vs. weight (Compare Earth to the moon.) | Mass is the same everywhere, but objects weigh less on the moon than on Earth due to the weaker gravitational pull on the moon. |
| Like ___________, opposites _________. | Like REPELS, opposites ATTRACT. |
| What is static electricity? | The buildup of electric charge on an object |
