| Kinetic energy | the energy of motion, or energy in use |
| Poential energy | is the enrgyan object has because of where it is or because of its conditions |
| Electric charge | when an object gains or loses electrons |
| Electric force | The attraction or repulsion of objects due to their electric charges |
| Conductor | Material that conducts electrons easilu |
| Electric Circuit | any path along which electrons can flow |
| Insulator | a material that doesn't carry electrons |
| Resistors | A material that resists the flow of electrons |
| Electromagnet | A temporary magnet made by passing an electric current through a wire coiled around an iron bar |
