| acetate | A type of plastic used in photographic film and overhead transparencies. |
| action-at-a-distance forces | Forces that can have an effect on an object without touching it. |
| charging by conduction | Process of transferring charge between objects by touching or rubbing. |
| charging by induction | Process of rearranging electrons on a neutral object by bringing a charged object close to it. |
| conductors | Materials that allow electrons to move freely on and through them. |
| contact forces | Forces that have an effect only on objects that they touch. |
| coulomb | The unit of electric charge, named after the French physicist Charles Coulomb; one coulomb is the amount of charge passing a point in one second when one ampere of current is flowing. |
| electric force | A push or pull between charged objects. |
| electrons | Negatively charged particles surrounding the positive nucleus. |
| force | A push or pull exerted on an object. |
| grounding | Connecting a conductor so that electric charge flows into Earth's surface. |
| insulators | Materials, such as glass, plastics, ceramics, and dry wood, that do not allow electrons to move easily on or through them. |
| laws of static charge | Physical laws that state that like charges repel, opposite charges attract , and neutral objects attract charged objects. |
| static charge | An electric charge that can be collected and held very nearly fixed in one place. |
