positive
2. What do you call a charge that stays on an object?
static electricity
3. Which kind of charges move? positive or negative
negative
4. How do 2 objects with different charges react to each other?
They attract, or pull each other.
5. How do 2 objects with the same charge react toward each other?
They repel, or push away from each other.
6. What are the parts of the circuit system in a flashlight?
battery, switch, and a lightbulb
7. Why does one disconnected bulb cause the other lights to go out in a series circuit?
There is only one path for the current to follow.
8. How does removing one bulb from a parallel circuit affect other bulbs in the circuit?
The other bulbs can still light because current continues to flow along the path.
