10. This is what a positively charged object will do to another positively charged object.

11. What is “repel”?

12. This is how the charges of an electron and proton compare.

13. What are “equal and opposite”?

14. These two things determine the strength of the force between two charged objects.

15. What are “the size of the charges and the distance between them”?

16. This is a diagram of an object that has been polarized.

17. What is - +

18. This type of charging involves two object the come in contact and end up with opposite charges.

19. What is “charging by friction”?

20. T This is what charging by non-contact is called.

21. What is “charging by induction”?

22. Charge does not flow freely through these materials.

23. What are “insulators”?

24. This type of charging occurs between objects that come in physical contact and then both have the same charge.

25. What is “charging by contact”?

26. These materials share properties of both conductors and insulators.

27. What are “metalloids”?

28. This is a diagram the demonstrates how two uncharged Electrophorus devices can be charged by induction with a positively charged Electrophorus.

29. What is   + - + + + - - +

30. This is where all electricity wants to flow.

31. T What is “the ground”?

32. These are the units of potential difference.

33. What are “volts”?

34. This type of device converts kinetic energy to electrical energy.

35. What is a “generator”?

36. This type of current is more practical for smaller electronic devices.

37. What is “direct current (DC)”?

38. This is the relationship between current and resistance for a circuit.

39. What is an “inverse relationship”?

40. All magnets must have two of these.

41. What are “poles”?

42. This is the region around a magnet where its effects may be felt.

43. What is the “magnetic field”?

44. This is the type of magnet that has domains that align and un-align in the presence of an external magnetic field.

45. What is a “temporary magnet”?

46. These are two ways to strengthen an electromagnet.

47. What are “increasing the number of current carrying coils and increase the current traveling through the coils”?

48. This is the field line pattern created when the unlike poles of two different bar magnets are brought near but not in contact with each other.

49. What is

50. This device converts chemical energy into electrical energy.

51. What is a “battery or a cell”?

52. This is the relationship between potential difference and current for a circuit.

53. What is a “direct relationship”?

54. This is a diagram of two bulbs connected in series to a battery.

55. What is

56. This device is made of a conductor attached to an insulator. The insulator serves as a handle so that you can pick up the device without touching the conductor. This device is called...

57. What is “an electrophorus”?

58. This was the name given to naturally occurring magnetic stones that were used for early navigation.

59. What are “leadstones or lodestones”?

60. Daily Double!

61. This type of device converts kinetic energy to electrical energy.
