Potential Energy
is defined as the ability to do work by virtue of position or condition.
work
Energy in the form of ____________ by an external force is needed
_________ must be done by an external force to move an object against nature - from low potential energy to high potential energy.
To move a charge in an electric field against its natural direction of motion would require ______.
againts
Moving ______ the NATURAL FLOW (of direction) of the ELECTRIC FIELD (dependent on the charge) will REQUIRE WORK.
along
Moving _____ the NATURAL FLOW (of direction) of the ELECTRIC FIELD (dependent on the charge) DOESN’T REQUIRE WORK.
electric potential energy
___________ depends on the charge of the
object experiencing the electric field.
The greater the charge on the “test charge,” the greater
the electric potential energy.
The stronger the electric field, the more energy a
charge would need to move about the electric field.
electric potential
is also known as “electrostatic potential”, “potential”, “voltage”, sometimes “potential difference
The amount of work needed to move a test charge (q0 ) from one point to another in an electric field.
relative measure
Electric potential is a _________ of how strongly a charge will be pushed away from or towards the location of the potential.
Electric potential measures the potential/voltage at one spot relative to the potential/voltage to the other spot (potential difference)
