Segment D: Electrical Potential Energy and Electrical Potential
Segment D: Electrical Potential Energy and Electrical Potential
We differentiate between the concepts of electric potential energy and electric potential by exploring electric potential energy qualitatively, looking at a charge between two parallel plates, and solving for electric potential in an example problem.
Science
Obtain, evaluate, and communicate information about electrical and magnetic force interactions.
Construct an explanation based on evidence of the behavior of charges in terms of electric potential energy.
-Compare and contrast electric potential energy and gravitational potential energy.
-Relate the law of conservation of energy to electric potential energy and kinetic energy for a charge between charged parallel plates.
-Differentiate between electric potential energy and electric potential.
-Understand that the electric potential energy a charge possesses is related to the electric field it is in and its magnitude of charge.
-Understand that electric potential energy and electric potential are scalar quantities.
electric field (E) - a region around a charged particle or charged object within which a force is exerted on other charged particles or charged objects.
electric potential (V) - also known as voltage, the electric potential energy per unit charge; the SI unit is the volt (V).
electric potential energy (PEE) - energy stored by electric charges; the energy that a charge in an electric field possesses, which gives it the ability to do work; the SI unit is the joule (J).
kinetic energy (KE) - the energy of motion; equal to one half times mass times the square of the velocity of an object.
