Homework Help: Work of gravity

  1. Jun 15, 2010 #1
    1. The problem statement, all variables and given/known data
    ( True / False ) When two massive objects are moved directly away from each other the work done by the force of gravity between the objects is positive for one of the objects and negative for the other.

    3. The attempt at a solution

    i believe the answer to be false because both will always be negative

    Your reasoning is OK, but always? What if the objects are moved closer together?
