Potential Energy and Work in an Electric Field (HSC SSCE Physics): Flashcards

$V = U/q$ (potential energy per unit charge)

Volt (V), where $1 ext{ V} = 1 ext{ J C}^{-1}$

$W = Eqd$

$Delta V = Delta U/q$

$Delta U = qDelta V$

$E = -Delta V/d$

$ext{V m}^{-1}$ (equivalent to $ext{N C}^{-1}$)

Infinite separation between charged objects

$1 ext{ eV} = 1.6 imes 10^{-19} ext{ J}$

Always perpendicular to each other
