Show Answers:

  1. Electricity
    A form of energy that results from the interaction of particles, such as electrons or protons
  2. Static charge
    • Static electricity
    • an electrical 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 rubbing against each other, producing a net static charge on each object
  4. Electrostatic series
    A list of materials that have been arranged according to their ability to hold onto electrons

    • glass
    • human hair
    • nylon
    • wool
    • fur
    • silk
    • cotton
    • lucite
    • rubber ballon
    • polyester
    • foam
    • grocery bags
    • ebonite
  5. Insulator
    A material in which electrons can not 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 of electrons to 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 electrical charge
  10. Charging by contact
    Generating a net charge on  a neutral  object by touching it with a charged object
  11. Laws of electric charge
    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 other objects
  13. Induced charge separation
    The movement of electrons in a substance, caused by the electrical field of a nearby charged object that is not in direct 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 if a building and connected to the 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
