| electric energy | What is produced by the movement of electrons? |
| electric charge | an object has this when it gains or loses electrons |
| negative electric charge | an object has this when it gains electrons |
| positive electric charge | an object has this when it loses electrons |
| electric force | the attraction or repulsion of objects |
| electric current | the flow of electrons |
| conductor | material that conducts, or carries, electrons easily |
| static electricity | the potential electric energy of charged objects; electrons do not move with this type of electricity |
| electric circuit | any path along which electrons can flow |
| insulator | a material that doesn't carry electrons |
| copper, aluminum, and other metals | these materials are good conductors |
| rubber, plastic, glass and air | these materials are good insulators |
| resistors | materials that resist, but don't completely stop, the flow of electrons |
| dragging your feet across a carpet or rubbing a balloon on your hair | these activities can cause electric charges |
| electromagnet | a temporary magnet made by passing an electric current through a wire coiled around an iron bar |
