Electrical or kinetic energy?

  1. Jun 19, 2007 #1
    If I know the charge on a particle and I know that it has initial speed of zero and I also know that it is passed through a potential difference of 100kV, can I say that its change in kinetic energy is

    deltaE = charge of particle(q) x potential difference(100kV)

    Or is this equation just used for finding electrical energy?

    Both. The electrical energy does work on the particle, meaning its kinetic energy increases. So, yeah, it can be used as both (assuming there's only an electro-static potential and no other forces involved).
