Show Answers:

  1. Electricity Definition
    A form of energy that results from the interaction of charged particles, such as electrons or protons
  2. Static Charge/Electricity definition
    an electric charge that tends to stay on the surface of an object, rather then flowing away quickly
  3. Charging by friction definition
    a process in which objects made from different materials rub against each other, producing a net static charge on each object
  4. Electrostatic Series
    a list of materials that have been arranged according to there ability to hold onto electrons
  5. Insulator
    a material in which electrons cannot move easily from one atom to another
  6. Conductor
    a material in which electrons can move easily between atoms
  7. Semiconductor
    A material in which electrons can move fairly well between atoms
  8. Ground
    An object that can supply a very large number electrons from, a charged object, thus neutralizing that object
  9. Electroscope
    a device for detecting the presence of an electric charge
  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 around a charged object, where the effects of its charge can be felt by other objects
  13. Induced charge separtation
    the movement of electrons in a substance, caused by the electric field of a near by charged object that is not in direct contact with the substance
  14. Ion
    a positively or negatively charged atom or group of atoms
  15. Lighting rod
    a metal sphere or a point that is attached to the highest part of a building and connected to ground
  16. Electrostatic Precipitator
    a type of cleaner that removes unwanted particles and liquid droplets from a flow of gas
  17. Van de Graaff Generator
    a device that accumulates very large charges
  18. Radiation Dosimeter
    a small device that detects and measures exposure to radiation
