Atwood machine

  1. Jun 12, 2007 #1
    1. The problem statement, all variables and given/known data
    Simple question I'm sure, but I want clarification if possible. If you do an experiment with the Atwood machine and you need to calculate 'g', should it be close to 9.8 m/s^2 ?

    2. Relevant equations

    No equations necessary, theoretical question. I would think the Atwood machine is trying to demonstrate that g is actually 9.8m/s^2 ?

    3. The attempt at a solution

    In reality, the pulley and string have mass, so the experimental acceleration will be less than the theoretical acceleration of the system

    My 'g' is calculated to be about 7.1 m/s^2, so its good to know it should be less than 9.8.
