Q

an electric charge is acquired when two bodies is rubbed it
this interaction between charges is summarized in the law of electrical charges

A

Friction

17
Q

amount of energy

A

Quantum

18
Q

the charge is equal to 0 or multiple of the basic unit of the charge
electric charge symbol - q

A

Quantized

19
Q

the name of particles that electrically charge

A

Ion

20
Q

Electrically neutral

A

atom

21
Q

Electrically charge

A

ion with inbalance protons and electrons

22
Q

negative (nonmetals become anion)

A

Anion

23
Q

positive ( metals become cation)

A

Cation

24
Q

is a list of common materials that were experimented or found to behave in
a predictable way

A

Triboelectric series

25
Q

are substances that have free electrons and allow charges ( e ) to move freely
through them

A

Conductors

26
Q

-the accumulation of electric charge on a surface of or within a material
- the shock happens when the extra electrons move and are released or discharged from an
object
- the charge doesn’t have to be moving, its still there even its resting on an object
example of electrostatic force:

A

Static Electricity

27
Q

is a material electrons can easily travel across

A

Conductor

28
Q

like car tire, a material that resists the movement of charge

A

Insulator

29
Q

that ranks materials on how easily they give up or receive electrons

A

Triboelectric series

30
Q

is one way that objects can accumulate an electrostatic charge

A

friction

31
Q

the transfer of charge by direct contact

A

Conduction

32
Q

a device that shows how charge accumulates, it has metal sphere on the top
connected to two metal foil leaves at the bottom by a metal rod, the leaves will either repel each
other or attract depending on the charge they are given

A

Electroscope

33
Q

charging a neutral object by bringing a charged object closed to but not touching the
object

A

Induction

34
Q

droplets suspended in the air

A

Aerosol

35
Q
  • gigantic electrostatic machines
    -can capture up to a large percentage of the particles from the burning material though some
    pollution does escape
    -that first charge dirt particles negatively and then capture them on a positively charged plate
    where they can’t escape into the air
A

Precipitators

36
Q

states that electric charge cannot be created or destroyed but
can be transferred from one object to another

A

Law of conservation of charge

37
Q

is conservative, that means it cannot be created or destroyed

A

electrostatic force

38
Q

s a form of electricity in which charge rests on an object until another charge
makes it move

A

Static electricity

39
Q
  • is the attraction between attraction or repulsion of electrons and protons
    -some materials are insulators and some are conductors
    -objects can accumulate charge by friction, induction, conduction
A

Electrostatic force
