Homework Help: Net force of a system

  1. Nov 22, 2009 #1
    1. The problem statement, all variables and given/known data
    Does net force on a system depend on forces that are internal to that system.

    2. Relevant equations

    My problem with understanding this is I don't know any equations that relate net force, external force and/or internal force.

    3. The attempt at a solution

    My guess is that internal work doesn't have to do with the net work of the system but without an equation I can't know sure. So I am not aking for the answer, I would just like an equaion to analyze because I can't find one.
