  1. Electricity
    A form of energy that results from interaction of charged particles, such as electrons or protons
  2. Static Charge
    • An electric charge that tends to stay on the surface of an object rather than flowing away quickly
    • Electric charge that remains "static" or doesnt move
  3. Charging by friction
    • A process in which objects made from different materials rub against each other, producing a net static charge on each
    • Involves the transfer of electric charge by rubbing or friction
  4. Electrostatic series
    List of materials that have been arranged according to their ability to hold on to electrons
  5. Insulator
    • A material in which electrons cannot move easily from one atom to another
    • Materials that make it hard for electrons to transfer
  6. Conductor
    Materials in which electrons can move easily through
  7. Semiconductor
    Materials in which electrons can move fairly well through
  8. Ground
    • Object that can supply a very large number of electrons to or can remove a very large number of electrons from, a charged object, thus neutralizing the object
    • An object that makes another object neutral through supplying/removing a very large number of electrons from a charged object
  9. Electroscope
    A device for detecting presence of an electric charge
  10. Charging by contact
    Generalizing a charge on a neutral object by touching it with a charged object
  11. Laws of electric charges
    Laws that describe how two objects interact electrically when one or both are charged
  12. Electric field
    • A property of charged objects of the space around a charged object where the effect of its charge can be felt by other objects
    • a region around a charged particle or object within which a force would be exerted on other charged particles or objects.
    • An area around a charged object in which a force would be applied on other objects
  13. Induced Charge Seperation
    • the movement of electrons in a substance, caused by the electric field of a nearby charged object, without direct contact between the substance and the object
    • movement of electrons caused by the electric field of a nearby object without direct contact
  14. Ion
    A charged atom or group of atoms
  15. Lighting rod
    A metal sphere or point, attached to the highest part of a building and connected to the ground
  16. Electrostatic precipitatior
    A type of cleaner that removes unwanted particles and liquid droplets from a flow of gas
  17. Van de Graff generator
    A device that accumulates very large charges
  18. Radiation Dosimeter
    A small device that detects and measures exposure to radiation
