| Electricity | Flow of electric current in a circuit. |
| Electrical charge | An object that ha an excess amount of either positive or negative charges. |
| Frictional force | The force that results from relative motion between objects (like the wheel and axle of a car) |
| Static electricity | A buildup of either postive or negative charge; consists of isolated motionless charges, like those produced by friction. |
| Electric field | Area around a charged object is affected by its charge |
| Electrical force | The force that charged materials or objects exert on each other. |
| Conductor | Material that rearranges well. |
| Insulator | Material difficult for material to rearrange. |
| Conductivity | The transfer of thermal energy by the direct contact of particles of matter. |
| Semiconductor | Material between conductor and insulator in its ability to carry current. |
| Discharge | Brief flow of electrons from a charged object to the rearranged object. |
| Electroscope | An instrument that is used to detect electrical charge. |
| Circuit | The structures that provide closed paths through which electricity travels. |
