Potential function

  1. May 2, 2009 #1
    1. The problem statement, all variables and given/known data

    If I know the potential function if a vector F can I calculate the line integral from point A to B using that potential function?

    2. Relevant equations



    3. The attempt at a solution

    just based on my understanding if I have the potential function then the line integral is just g(Q) - g(A). Where A is the starting point of the curve and Q is the ending point.. g is the potential function.. correct?

    Right again. The line integral is path independent if the vector field has a potential.
