303444464Equation relating Electric Potential Energy and Electrical Work∆U = -W
303444465Electric Potential between two _?_ charges is ZERO. (LIKE or OPPOSITE)Electric Potential between two _OPPOSITE_ charges is ZERO.
303444466A positive charge naturally accelerates from a region of _?_ to _?_ electric potential. (HIGHER or LOWER)A positive charge naturally accelerates from a region of _HIGHER_ to _LOWER_ electric potential.
303444467A negative charge naturally accelerates from a region of _?_ to _?_ electric potential. (HIGHER or LOWER)A negative charge naturally accelerates from a region of _LOWER_ to _HIGHER_ electric potential.
303444468When a charge moves naturally the work done by the electric force is _?_ and the potential energy change is _?_. (POSITIVE or NEGATIVE)When a charge moves naturally the work done by the electric force is _POSITIVE_ and the potential energy change is _NEGATIVE_.
303444469When a charge moves UNNATURALLY the work done by the electric force is _?_ and the potential energy change is _?_. (POSITIVE or NEGATIVE)When a charge moves UNNATURALLY the work done by the electric force is _NEGATIVE_ and the potential energy change is _POSITIVE_.

303444471A surface or line upon which all electric potentials are equalEquipotential
303444472What type of material has an equipotential surface? Why?CONDUCTORS have EQUIPOTENTIAL SURFACES because charge spreads out evenly across the surface.
303444473Electric fields are _?_ to EQUIPOTENTIAL LINES.Electric fields are _PERPENDICULAR_ to EQUIPOTENTIAL LINES.
303444474Electric Fields are directed towards regions of _?_ electric potential. (INCREASING or DECREASING)Electric Fields are directed towards regions of _DECREASING_ electric potential.
303444475Equation that expresses the electric potential at a given distance from a chargeV = k (Q)/(r)
