| Question | Answer |
|---|---|
| discharge | the sudden movement of electrical charges from one object to another object |
| static electricity | the build up of electrical charge on an object or material |
| electric current | the flow of electrical charges |
| circuit | a path through which electric current can flow |
| series circuit | a circuit in which electric current flows in the same direction along a single path |
| parallel circuit | a circuit in which electric current flows through more than one path |
| resistor | objects that resist the flow of electric current |
| electromagnet | a magnet formed when electric current flows through wire, wrapped in coils, around an iron bar |
| motor | a device that changes electricity or other forms of energy into mechanical energy |
| generator | a device that produces alternating current by spinning an electric coil between the poles of a magnet; changes motion into electrical energy |
| balanced forces | forces that cancel each other out when acting together on a single object |
| unbalanced forces | forces that do not cancel each other out when acting together on a single object |
