  1. What is Electricity?
    • A form of energy that results from the interaction of charged particles
    • i.e.- Protons, Electrons
  2. What is Static Charge (Static Electricity)?
    Electric charge that remains "static" or doesn't move
  3. What is Charged by Friction?
    • Involves the transfer of electric charge by rubbing or friction
    • i.e.- Combing Hair
  4. What is the Electrostatic Series?
    • Used to determine the kind of electric charge produced on each substance when two substances are rubbed together
    • Image Upload 1
    • (Another good diagram is also available on page 405 in the textbook for studying)
  5. What is an Insulator?
    • A material in which electrons cannot move easily from one atom to another atom
    • i.e.- Vinyl, Silicon, Teflon.
  6. What is a Conductor?
    • A material in which electrons can move easily atoms
    • i.e.- air, glass, human body
  7. What is a Semiconductor?
    • A material in which electrons can move fairly well between atoms
    • i.e. lead, cotton, wool
  8. What is Ground?
    An object that can supply a very large number of electrons to, or remove a large number of electrons from, a charged object, thus neutralizing the object
  9. What is an Electroscope?
    • A device for detecting the presence of and electric charge
    • Types- pith ball electroscope, metal leaf electroscope
  10. What is Charging by Contact?
    Generating a charge on a neutral object by touching it with a charged object
  11. What is the Law of Electric Charges?
    Laws that describe how two objects interact electrically
  12. What is an Electric Field?
    A property of the space around a charged object, where the effect of it's charge can be felt on other objects
  13. What is Induced Charge Seperation?
    The movement of electrons in a substance, caused by the electric field of a nearby charged object between the substance and the object
  14. What is an Ion?
    A charged atom or group of atoms
  15. What is a Lightning Rod?
    • A metal shpere or point, attached to the hightest part of a building and connected to the ground
    • Image Upload 2
  16. What is a Electroscostatic Precipitator?
    A type of cleaner that removes unwanted particles and liquid droplets from a flow of gas
  17. What is a Van de Graff Generator?
    A device that accumulates very large charges
  18. What is a Radiation Dosimeter?
    A small device that detects and measures exposure to radiation
