Applications of Static
100
The nucleus of an atom contains these
What are protons and neutrons
100
When electric charges are transferred by rubbing two different neutral materials together
What is charging by friction
100

The induced movement of electrons in a neutral object by a nearby charged object is called _____________

What is induced charge separation

or temporary induction

100

The three components needed for a lightning rod are _____, __________, and ___________.

Lightning rod, grounding wire and grounding rod.

200
An object that has more electrons than protons
What is a negatively charged object

Why doesn't your skin become charged when you rub your hands together?

The material is in the same position in the electrostatic series. Skin = Skin, neither material steals electrons. 

200
The object that induces a charge keeps its original charge and the induced object receives the ________ charge
What is an opposite charge
200

Electric discharge often occurs when there is ___________. 

A large build up of charge on one object

300
If an atom does not have an equal number of protons and electrons, it has an ____________
What is electric charge
300
_______________ occurs when two objects with different electric charges come in contact and electrons move from one object to another
What is charging by conduction
300
This must be done to permanently charge an object through induction
What is grounding
300

Why does an electric charge build up on cars?

There is friction between two objects; the car and the air.

400

If two neutral objects are placed near each other they will___________.

Do nothing

400
Connecting an object to a large body that is capable of effectively removing an electric charge that the object might have
What is grounding
400

When a positive object is brought near a grounded object electrons will_____________.

Move from the ground into the neutral object.

Why is it less important to follow static safety for water than it is for oil or air?

Water is typically a fair conductor so the electric charge spreads out.

500

If a negtive object and a neutral object are placed near each other ___________.

They will attract

500

What happens when two unevenly charged negative objects connect?

Electrons move from the object with the higher negative charge to the object with the lower charge. They end up with even charges.

500

Explain why a neutral object is attracted to a positive object.

The electrons in the neutral object move to the side of the object that is closer to the charged object. From this point on the "neutral object" has more electrons  closer to the positive object than protons. This means that the attractive force is stronger than the negative force.

How can static electricity be used to clean the air. 

Dust particles can be negatively charged then attracted to positively charged plates. When enough dust gathers together, it overcomes gravity and falls into a waste collection.
