  1. Electricity
  2. A form of energy that results from the interaction of charged particles, such as electrons or protons
    E.g. lightning, hydroelectricity, static electricity
  3. Static charge (static electricity)
  4. An electric charge that tends to stay on the surface of an object
    E.g. static electricity in your hair after rubbing a balloon against it
  5. Charging by friction
  6. Charging by friction
  7. Electrostatic series
  8. A list of materials that have been arranged according to their hold on to electrons
    E.g. glass is higher than ebonite
  9. Insulator
  10. A material in which electrons cannot move easily from one atom to another
    E.g. wood, glass, cloth
  11. Conductor
  12. A material in which electrons can move easily between atoms
    E.g. metal, ebonite, balloon
  13. Semiconductor
  14. A material in which electrons can move fairly well between atoms
    E.g. silk, cotton, lucite
  15. Ground
  16. 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
    E.g. the third “prong” on an outlet connected to ground water
  17. Electroscope
  18. A device for detecting the presence of an electric charge
    E.g. a metal leaf electroscope
  19. Charging by contact
  20. A process in which objects made from different materials rub against each other, producing a net static charge on each object
    E.g. touching a toaster with a fork
  21. Laws of electric charges
  22. Laws that describe how two objects interact electrically when one or both are charged
    E.g. opposites attract
  23. Electric field
  24. A property of the space around a charged object, where the effect of its charge can be felt by other objects
    E.g. the heat/electricity you feel near generators
  25. Induced charge separation
  26. 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
    E.g. a magnet pulls objects without touching them
  27. Ion
  28. A positively or negatively charged atom or group of atomsImage Upload
  29. Lightning rod
  30. A metal sphere or point that is attached to the highest part of a building and connected to the ground
    E.g. little rods all over the cn tower
  31. Electrostatic precipitator
  32. A type of cleaner that removes unwanted particles and liquid droplet from a flow of gasImage Upload
  33. Van de Graaff generator
  34. A device that accumulates very large charges
    E.g. the machines at the science centre that makes your hair stand on end
  35. Radiation dosimeter
    A smaller device that detects and measures exposure to radiationImage Upload
