Electricity
Materials can become electricity charged
Electirc charge is a property of matter
Electric charge
Property allows an object to exert an electric force on another object without touching i
Protons + electric charge Electrons- Electric charge
Electric Field
push or pull/repel or attract
The space around a particle through which an electric charge can exert this force
static charge are caused by the movement of electrons
Static Charge
Buildup of electric charge in an object caused by the presence of many particles with the same charge
How Materials Affect Static Charging
Skin,Glass,Hair,Nylon,Wool,Fur,Silk,Paper,Rubber,polyester
From Left to right give up more electrons
Charging by Contact
Charging by Induction
The buildup of charge without direct contact
Charge Polarization
Charges can move from one place to another
Static Charges have Potential Energy
Electric Potential Energy
Electric Potential
Amount of electric potential energy per unit charge at a certain position in an electric
volt
equal to one joule of energy per coulomb of charge
Electric current is a flow of charge
Electric cells supply electric current.
Electro Chemical cells
Primary cells
One Use Batteries
zinc, carbon rod, separator,terminal,
Allows flow of electrons
Storage Cell
Rechargeable battery
Lead peroxide,lead,mostly sulferic acid
Allows flow of electrons
