Electrostatic

Capacitor-a device that can store electric charge, and consists of two conducting objects (usually plates or sheets) placed near each other but not touching

Conductor-a material in which charges move through freely

Insulator-materials in which charge cannot move through freely

Proton-a subatomic particle with a positive electrical charge

Electron-a subatomic particle with a negative electrical charge

Induction-the process of charging a conductor by bringing it near another charged object

Coulomb’s Law-states that electric force is proportional to the product of two charges and inversely proportional to the square of the distance between them

Electric field-a region around a charged object

Electric field lines-lines pointing in the direction of the electric field around a charged object

Electroscope-a device that is used to detect the presence and magnitude of electric charge

Static electricity-the buildup of electric charge on the surface of objects

Potential difference-the work that must be performed against electric forces to move a charge between the two points in question divided by the charge
