Term
Proton
Definition
has a positive charge
Term
electric force
Definition
the attraction (pull) or repulsion (push) between electric charges (protons attract electrons)
Term
electron
Definition
has a negative charge
Term
repel
Definition
charges that are the same repel each other(move away)(protons repel protons)
Term
attract
Definition
charges that are different attract (pull toward) each other
Term
electric field
Definition
the area around a charged object where the object's electric force is put (exerted) on other charged objects
Term
electric field around a positive charge
Definition
the charges point OUT
Term
electric field around a negative charge
Definition
the charges point IN
Term
electric fields of two or more charges
Definition
each individual charge combines by repelling or attracting
Term
neutral object
Definition
each positive charge is balanced by a negative charge
Term
uncharged object becomes charged by
Definition
gaining or losing electrons
Term
static electricity
Definition
buildup of charges on an object
Term
law of conservation of charge
Definition
Charges that are not created or destroyed. They are just transferred to another object.
Term
friction
Definition
transfer of electrons from one object to another by rubbing (electrons from carpet to a sock)
Term
conduction
Definition
the transfer of electrons from a charged object to another object by direct contact (a charged sock touches skin)
Term
induction
Definition
movement of electrons to one part of an object by the electric field of another object (electrons on finger touch doorknob)
Term
electroscope
Definition
a tool that detects an electric charge
Term
static discharge
Definition
loss of static electricity as electric charges transfer from one object to another
Term
negative charged object PLUS a positive charged object =
Definition
electrons transfer until both objects have the same charge
