The magnitude of the electric force between two point charges is _______ ________ to the product of the charges
directly proportional
is said to exist in the region or space around a charged object, the source charge - it is the electric force per unit charge (N/C)
electric field
In electrostatic attraction, there is ____ between charges
work
per unit charge (V or J/C)
STORED ENERGY in a CIRCUIT
the energy NEEDED to MOVE AN ELECTRIC CHARGE against an electric field
electric potential energy
it is the AMOUNT of WORK needed to move an electric charge FROM ITS REFERENCE POINT to a specific point on the electric field
electric potential
is required to MOVE an ELECTRIC CHARGE that contains potential energy either towards an opposite charge or against a like charge
electric force
refers to the total kinetic and potential energies present in a system
law of conservation of mechanical energy
refers to the “rate of the flow of the electric field through a given SURFACE”
the property of an electric field relating to the measure of its strength
electric flux
a _______ charge within a region will have an outward electric flux passing through its surface.
positve
A _______ charge will have an inward electric flux through its surface
negative
The net electric flux going outward the surface of the region is _________ proportional to the magnitude of the net charge enclosed by that region.
directly
a law that states that the electric flux passing through a closed surface is EQUAL to the RATIO of TOTAL CHARGE enclosed by that surface to the permittivity of FREE SPACE
