Electrostatics 2
Key Points
Here are the key points for this webpage:
- Two charges ( positive and negative)
- + charge comes from protons, - from electrons
- Opposite charges attract, Like charges repel
- Electrons move, protons do not
- Everyday phenomenon can be explained by electrostatics.
Review of Key Concepts:
- Two charges ( positive and negative)
- + charge comes from protons, - from electrons
- Opposite charges attract, Like charges repel
- Electrons move, Protons Don't
- Charging by friction because one material likes e- more than other and pulls them away from the other
- Static Discharge - when the charge is soooo much that something that doesn’t conduct electricity does (spark, lightning)
- Grounding - the removal of extra charge by touching a larger object.
Movement of Charge Activities
Balloon Static Electricity |
For this activity, consider the following:
1) What charges are moving?
2) What causes the charges in the activity?
3) Why does the balloon stick to the wall?

John Travoltage Activity
For this activity, consider the follwing:
1) Where are the charges coming from?
2) Why do the charges spread out?
3) Why does the spark happen?
