Electricity
Materials Can Become
Electrically Charged.
Electric charge is
a property of matter.
Electric Charge
Characteristics: push, pull
Examples: protons, electrons
Definition:
a property that allows an
object to exert an electric
force on another object without
touching it
Nonexamples: neutron
Electric Field
Definiton:
the space around
a particle
Characteristics: strength is greater
when near a particle and weaker
farther away from the particle
Examples: proton, electrons
Nonexamples: neutron
Static charges are caused by
the movement of electrons.
Static Charge
a buildup of electric charge in
an object caused by the prescence
of many particles with the same charge
Charging by Contact
when two uncharges objects made of ceratin materials; such as rubber and glass; touch each other, electrons moce from one material to the other
occurs when one material's electrons are attracted to another material more than they are attracted to their own
How Materials Affect Static Charging
materials tend to give up electrons
to anything below it on the list an
accept electrons from anything above
it on the list
Charging by Induction
Induction
buildup of a charge without direct contact
can produce a temorary static charge
can leave an object with a stable static
charge if the elctrons cannot return to
their original distribution
Charge Polarization
when the negative charges of the within
atoms may shift to the side awau from the object
Technology uses static electricty.
