Conservation and Non-conservation energy

    My Teacher question is
    if the potential depends explicity on time t and/or on velocity v then energy of particle is not conserverd. Explain and prove.

    hmm im not too sure how right this is but

    any force crossed with the del operator equals 0 if a force is conservative

    which means it depends on position explicitly?
    ...hope that helps somehow
