  1. Electricity
    A form of energy that results from the interactions of charged particles, such as electrons and protons
  2. Static charge (static electricity)
    An electric charge that tends to stay on the surface of the object, rather than flowing away quickly
  3. Charging by friction
    When objects made from different materials rub
  4. Electrostatic series
    • A list of materials that have been arranged according to their ability to hold on to electrons
    • Closer to top has a weaker hold
  5. Insulator
    • A material in which electrons cannot move easily from one atom to another
    • I.e. wood, rubber, plastic (Non-metal)
  6. Conductor
    • A material in which electrons can move easily between atoms
    • I.e. Copper, aluminum (Main metal)
  7. Semiconductor
    • Non-metals in which electrons move fairly well
    • I.e. Silicon
  8. Ground
    An 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
  9. Electroscope
    • A device for detecting the presence of an electric charge
    • Metal leaf
    • Pith ball

  10. Charging by contact
    Generating a net 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 the space are a charged object, where the effect of its charge can be felt by other objects
    • Objects with greater net charges have stronger electric fields
  13. Induced charge seperation
    The movement of electrons in a substance, caused by the electric field of a nearby charged object, without direct contact

  14. Ion
    A charged group of atoms
  15. Lightning rod
    • A metal sphere or point, attached to the highest part of a building and connected to the ground
    • On top of CN Tower

  16. Electrostatic precipitator
    • A type of cleaner that removes unwanted particles and liquid droplets from a flow of gas
    • 1907 patented
  17. Van de Graaff generator
    A device that accumulates a very large
