1. Static Electricity Review

2. Which part of the atom can move from one atom to another?+ –
Proton (positive charge) +
neutron (neutral)
electron (negative charge) –
atom
nucleus

3. Which part of the atom can move from one atom to another?
The electron + – +
electron (negative charge) –
atom
nucleus

5. What happens to make an object have a negative charge?
If electrons > protons  negative charge (gains electrons)

6. What happens to make an object have a positive charge?

7. If electrons < protons  positive charge (lost electrons)

8. What are 3 ways to transfer electric charge

9. 3 ways to transfer electric charge
Conduction
Induction
Friction

10. Type of Electron Transfer when Objects make Contact

11. Conduction Excess electrons pass to a neutral object when touched

12. Type of Electron Transfer when Electrons move from a distance without contact

13. Induction Electrons transferred when a neutral object is near a charged object (in the electric field)

14. Type of Electron Transfer when Electrons are moved by force

15. Friction moving electrons by force
Type of Electron Transfer when Electrons are moved by force

17. What are Insulators?

18. Insulators
Insulators: materials that do NOT allow electrons to flow through them easily.
Insulators can be easily charged by friction as the extra electrons gained CANNOT easily escape.

19. Examples of Insulators?
Insulators: materials that do NOT allow electrons to flow through them easily.

20. Conductors and Insulators
Copper
Rubber
Aluminum
Cloth
Humans
Hair
Water

Copper
Rubber
Aluminum
Cloth
Humans
Hair
Water

Cloth
Humans
Hair
Water
Plastic

Glass
Paper

23. What is the difference between insulators and conductors?
Copper
Rubber
Aluminum
Cloth
Humans
Hair
Water
Plastic
Most metals
Glass
Paper

24. What do the built up electrons create around the charged object?

25. What do the built up electrons create around the charged object?
An electric field

26. What will happen?

27. What will happen?
X will repel like charges repel

28. What will happen?
Y will attract in a neutral object like charges repel and the opposites attract

29. What will happen?
Z will attract opposites attract

30. What will happen to the man?

31. How does the man get positively charged?

32. How does the man get positively charged?
He gets charged by friction

33. Why does the man get zapped?

34. Why does the man get zapped?
He is positively charged and the electrons jump to him during electric discharge

35. Why are many electrical objects grounded?

36. Why are many electrical objects grounded?
So extra electrons go to the ground and do not build up on materials to shock people

38. Maybe the caravan was struck by lightning.
The van and the balloon have opposite charges so they stick together.
The man is charged and has a lot of negative charges.

40. Why is her hair standing up?
