2
All matter is composed of it.
3
What are Atoms?
4
They are negatively charged and they are found in orbits circling around the nucleus of the atom
5
What are Electrons?
6
These are found in the nucleus of the atom. Their charges are either positive or no charge.
7
What are Protons and Neutrons?
8
An object with an equal number of protons and electrons.
9
What is a Neutral Object?
10
These subatomic particles move in space AND they can be added or removed from the atom?
11
What are Electrons?
12
An object with more electrons than protons
13
What is a Negatively-Charged Object?
14
It is what objects with like charges do
15
What is Repel?
16
The force exerted by an object with an electric charge
17
What is Electric Force?
18
Objects with like charges repel each other and objects with opposite charges attract each other
19
What is the Law of Electric Charges?
20
An imbalance of electric charges on the surface of an object
21
What is Static Electricity?
22
Two different neutral materials are rubbed together so that electric charges are transferred
23
What is Charging by Friction?
24
A list of materials arranged in order of their tendency to gain electrons
25
What is the Electrostatic Series?
26
Charging a neutral object by bringing another charged object close to – but not touching – the neutral object
27
What is Charging by Induction?
28
Connecting an object to a large body that is capable of removing an electric charge from an object
29
What is Grounding?
30
Charging an object by contact with a charged object
31
What is Charging by Conduction?
32
A large hollow sphere resting on the insulting cylinder, and inside the cylinder, a belt stretched over two pulleys.
33
What is a Van de Graaff Generator?
34
These are placed on the roofs of tall buildings to provide a safe path for lightning to follow to reach the ground while not damaging the buildings
35
What is a Lightning Rod?
36
An electric discharge that occurs between clouds OR between clouds and the ground
37
What is Lightning?
38
Rapid transfer of electric charge from one object to another object
39
What is Electric Discharge?
40
There are an excess number of these particles at the bottom of a thunder cloud
41
What are negatively-charged water particles?
42
A material that lets electrons move easily through it
43
What is a Conductor?
45
What is Charging by Conduction?
47
What is Charging by Friction?
48
A shift in the position of electrons in a neutral object that occurs when a charged object is brought near it
49
What is Induced Charge Separation?
50
A material that does not easily allow for the movement of electrons through it
51
What are Insulators?
