  1. Electricity
    Def: a form of energy that results from the interaction of charged particles, such as protons and electrons.
  2. Static Charge
    Def: an electric charge that tends to stay on the surface of an object, rather than flowing away quickly.
  3. Charging By Friction
    a process in which objects made from different materials rub against each other, producing a net static charge on each object.
  4. Electrostatic Series
    Def: a 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.
  6. Conductor
    A material through which electrons can flow 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 of electrons to, or can remove a very large number of electrons from, a charged object, thus neutralizing that object.
  9. Electroscope
    A device for detecting the presence of an electric charge.
  10. Charing 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 effect of its charge can be felt by others.
  13. Induced Charge Seperation
    the movement of electrons in a substance, caused by the electric field of a nearby charged object that is not in direct contact with the substance.
  14. Ion
    A positively or negatively charged atom or group of atoms.
  15. Lightning Rod
    A metal sphere or 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.
