Q

How can an object become charged?

A

An object becomes charged by friction, for example a balloon is rubbed on wool, now the wall is + and the balloon -
is gaining or losing electrons

Q

If an object gains electrons what will be its overall charge?

24
What is anything that takes up space and has mass called?
Matter
25
What tiny particles are all matter made up of?
Atoms
26
What charges does each atom contain?
Electrons, protons and neutrons
27
What charges do electrons have?
Negative
28
What charges do protons have?
Positive
29
What charges do neutrons have?
Neutral charge
30
Where are protons and neutrons found in an atom?
In the central core or nucleus
31
If electrons are not found in the nucleus where are they located?
They orbit around the nucleus
32
Explain why most objects are considered electrically balanced.
They are electrically balanced because they have the same number of electrons and protons
33
If an object loses electrons when it is rubbed, it is said to have a _________ charge because it has more protons
Positive
34
Like charges or charges that are the same, occur when two objects both became __________ or _________ charged
Positive and negative
35
When one object becomes positively charged and the other becomes negatively charged they are considered to be _________ charges
Unlike
36
What are three methods in which charges are transferred?
Friction, conduction and induction
37
True or false? | An electric field extends outward from every charged particle
True
38
Because of an electrical field, charged particles that are ___________ would be pulled together
Different or opposite
39
What instrument has two thin metal leaves and is used to detect an electrical charge?
Electroscope
40
Cellophane was stuck on the wall then wool was rubbed on it then taken off and it repel but when she put her arm in the middle it attracted. Name the method of charging
Friction
41
The balloon was rubbed on hair then the balloon was taken away and the hair was attracted to the balloon and was sticking up to touch the balloon. Name the method of charging
Friction
42
The ripped paper started stacking up to touch the balloon because it was attractive. Name the method of charging
Induction
43
The comb was near the water and was curving closer to the comb to be attracted to it. Name the method of charging
Induction
44
The balloon was rubbed and then stuck on the wall then it stayed. Name the method of charging
Conduction
45
The balloon was robbed and then it was put on the rod and the leave spread apart. Name the method of charging
Conduction
46
The balloon was rubbed then it was put near the soda can and they can removed. Name the method of charging
Induction
47
If an object is rubbed and it loses electrons, what kind of charge will it have?
Positive
48
Explain why the object that is rubbed and loses electrons will have a positive charge?
because it has more electrons than protons
49
If it object gains electrons when it is rubbed, what kind of charge will it have?
Negative
