Static Electricity Flashcards
1
Q
Why can electrons be rubbed off a material?
A
This is because unlike protons electrons are free to move around because it only surrounds the nucleus.
2
Q
Charging by friction
A
- charging a material by rubbing
- When electrons are rubbed off a material, it becomes positively charged
- Material gains electron and becomes negatively charged
3
Q
Uncharged Materials
A
When a material is uncharged, it has the same number of electrons and protons.
4
Q
Charged Materials
A
When two materials are rubbed against each other, one becomes positively charged (lost electrons), and the other becomes negatively charged (gained electrons)
5
Q
The attraction between charged and neutral objects
A
When the charged object is brought near the neutral object, the electrons in the neutral objects do not come off but instead repel due to the opposites’ attract, and the same repel rule.
