Cards

Term
NEGATIVE
Definition
the conceptual charge of an electron
Term
positive
Definition
the conceptual charge of a proton
Term
CONDUCTORS
Definition
charges are loosely bound to the nucleus and free to move from atom to atom
Term
INSULATORS
Definition
charges are tightly bound to one nucleus
Term
CHARGING BY FRICTION
Definition
the transfer of a charge by rubbing electrons of one object and putting it on another; occurs between insulators
Term
CHARGING BY CONDUCTION
Definition
charging a conductor by contact (no rubbing necessary) [complete transfer]
Term
CHARGING BY INDUCTION
Definition
charging through polarization without contact (separates charges); then grounding
Term
GROUNDING
Definition
the act of allowing charges to move off or onto a conductor by touching it
Term
ELECTROSTATICS
Definition
the study of static electricity or stationary electrical charges
Term
CHARGED
Definition
an object that has an unbalanced amount of electricity is said to be this (either positive or negative)
Term
COULOMB
Definition
SI unit for charge
Term
ELECTRICAL POLARIZATION
Definition
when one side of the atom or molecule is induced to be slightly more positive or negative than the opposite side
Term
ELECTRICAL FORCE
Definition
attractive and repulsive forces acting on and object.
Term
COULOMB'S LAW
Definition
electrical force is indirectly proportional to the square of the distance between charges and directly proportional to the amount of charge on each
Term
-1.6 x 10^(-19) C
Definition
the actual charge of an electron
Term
+1.6 x 10^(-19) C
Definition
the actual charge of a proton
Term
ELECTRIC FIELDS
Definition
the force per charge at a given location in space; points in the direction of a force experienced by a positive test charge (vector)
Term
ELECTRIC FIELD LINES
Definition
point in the direction of the electric field vector (away from positive, and towards negative)
Term
LAW OF CONSERVATION OF CHARGE
Definition
the net charge of a system remains constant
