Grade 10: Electrostatics
| Term | Definition |
|---|---|
| Neutral | An object that has an equal number of electrons and protons (no net charge). |
| Positively charged | Objects are electron deficient. |
| Negatively charged | Objects have an excess of electrons. |
| Tribo-electric charging | A type of contact electrification in which certain materials become electrically charged after they come into contact with different materials and are then separated (such as through rubbing). |
| Principle of conservation of charge | The net charge of an isolated system remains constant during any physical process. |
| Principle of charge quantization | All charges in the universe consist of an integer multiple of the charge on one electron. |
| Polarisation | The partial or complete polar separation of positive and negative electric charge in a system. |
