ELECTRIC POTENTIAL

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)
