Forces help

  1. Nov 18, 2007 #1
    1. The problem statement, all variables and given/known data
    THe question says 3 forces, F1,F2,F3 act on an object. The net force acting on the object is 0, so it does not move.
    1.If we are now on Mars where gravity is now 3.72m/s2 will the forces still be balanced?

    2. The other question asks if we were on Mars g=3.72m/s2, compared to when we wre on earth will the mass of the object increase,decrease,stay the same.

    2. Relevant equations

    3. The attempt at a solution

    Answers I thought were right

    what do you guys think?

    1) How do you know that gravity isn't one of those forces? I think there are two cases to consider.

    2) What is the difference between mass and weight?
