When a charged particle moves between two locations with different electric potentials, the resulting change in the electric potential energy of the particle-field system can be found by multiplying the charge by the electric potential difference between the locations.

Topics: Electric potential energy from potential difference · Energy conservation: from potential energy to speed · Negative charges and the sign of ΔU · The electron volt · Worked example: finding the final speed · Conceptual example: moving a charge into a charged sphere

Connecting electric potential and field using calculus | AP Physics | Khan Academy

At a given location in an electrostatic field, the electric field component in a particular direction equals the negative derivative of electric potential with respect to position in that direction. The change in electric potential between two points equals the negative integral of the dot product of the electric field and the displacement along a path connecting them. This change is independent of the path chosen.

Equipotential lines represent lines of equal electric potential. These lines are also referred to as isolines of electric potential. Isolines are perpendicular to electric field vectors. An isoline map of electric potential can be constructed from an electric field vector map, and an electric field map may be constructed from an isoline map. An electric field vector points in the direction of decreasing potential. There is no component of an electric field along an isoline.

Topics: Connecting electric field and potential · Potential changes in nonuniform fields · Understanding equipotential surfaces · Equipotential surfaces around a point charge · Visualizing potential with topographic maps · Potential of conductors in equilibrium

From ROI to "Return on Learning": A District's Khan Academy Story

11K views · 3w ago · 47:24

Some districts are banning AI outright. West Hempstead UFSD went the other direction — deliberately, with guardrails, and with a clear line about what belongs in elementary school and what doesn't. In this 47-minute conversation, Sal Khan asks Superintendent Dan Rehman and his teachers the uncomfortable questions: screen time, cheating, cognitive offloading, and whether any of this is appropriate for young children.

Electric potential describes the electric potential energy per unit charge at a point in space. The electric potential due to multiple point charges can be determined by the principle of scalar superposition of the electric potential due to each of the point charges. The electric potential difference between two points is the change in electric potential energy per unit charge when a test charge is moved between the two points.
