1

positively charged molecule

proton

New cards
2

negatively charged molecule

electron

New cards
3

a law stating that like charges repel and opposite charges attract (helps us measure electrical force)

What is Coulomb’s Law?

New cards
4

pulling electrons from one material to another

Charge by friction

New cards
5

bring charged objects near, but not touching

Charge by induction

New cards
6

charging one side of the atom or molecule (one side of the atom is more (+) or (-) than the other

Charge by Polarization

New cards
7

there is a negative charge

What happens when an object is charged by fur?

New cards
8

there is a positive charge

What happens when an object is charged by silk?

New cards
9

charge easily (silver and silicon)

Conductors

New cards
10

hard to charge (glass)

Insulators

New cards
11

non-flowing charges

what are electrostatics?

New cards
12

Amount of free electrons (-)

What are conductors and insulators determined by?

New cards
13

energy a charge has due to its location

(greater when closer) ;measured in volts

Electrical Potential

New cards
14

the current through each of the components is the same, and the voltage across the circuit is the sum of the voltages across each component

Series circuit

New cards
15

the voltage across each of the components is the same, and the total current is the sum of the currents through each component

Parallel circuit

New cards
16

a force that acts at a distance due to a magnetic field. This field is caused by moving electrically charged particles or is inherent in magnetic objects such as magnets

magnetism

New cards
17

our magnetic field protects us from the solar wind from the sun

magnetic fields

New cards
18

allowing charges to flow off or on a conductor by touching it will a conductor

grounding

New cards
19

same number of positive and negative charges in an atom which cancel each other out

neutral charge

New cards
20

affect an electric field

Magnitude and direction

New cards
21

An electric charge is created when electrons are removed from an object. When negative charges are added to an object it becomes negatively charged and when they are removed they become positively charged.

What happens when you remove a charge from a charged object?

New cards
22

electric current (the greater the current the greater the magnetic field)

What produces a magnetic field?

New cards
23

voltage and resistance

What does the amount of current in a wire depend upon?

New cards
24

potential difference in a charge

What is voltage?

New cards
25

Resistance to a flow of charge

What is resistance?

New cards
26

Thickness, length and temperature of a wire

What does resistance depend upon?

New cards
27

must have a constant flow that is caused by a constant voltage

Electricity

New cards
28

less resistance

What happens when the thickness of a wire increases?

New cards
29

more resistance

What happens when the length of a wire increases?

New cards
30

more resistance

What happens when the temperature of the wire increases?

New cards
31

it attracts electricity

why do we use lightening rods?

New cards
32

hold charges well (house and trees)

Spheres

New cards
33

no charge buildup (charged are easily leaked)

Sharp objects

New cards
34

The space between objects (interactions of objects without touching)

What is a force field?

New cards
35

a charge alters the space around an object in such a way that another charge in the region experiences a force

How is an electric field created?

New cards
36

the space around an electric charge that is permitted by an electric field

What is an electric field?
