Help with Force

  1. Nov 20, 2007 #1
    Help with "Force"

    1. The problem statement, all variables and given/known data

    Overall, I would just like some advice on how to tackle a variety of Force based questions.
    A few of them that have left me lost involves finding Tension and Acceleration of a pulley system.


    2. Relevant equations

    Equations surrounding Newton's 2nd law, not working with friction. =)
    m2g-m1g=(m1+m2)a


    3. The attempt at a solution

    I would just appreciate some advice on how to tackle these problems and when to use equations like "m2g-m1g=(m1+m2)a or T-MG=MA.

    Thank you.

    It's kind of difficult to give generic advice without a specific problem to refer to. It might be worth your while to work through the example problems on this page: Standard Newton's Laws Problems

    I find that when I have to solve these problems
    - Draw the free-body diagram
    - label everything
    - solve for your unknown variables
    - and see if u can re arrange ur equation or simplify it
