An Atwood's Machine lab question?

  1. Sep 25, 2004 #1
    I have a question...When you take times/measurements in lab, is the %difference supposed to be 40-50%? That seems like a lot to me! My lab partner took the measurements and I am suposed to do the calculations at home, but I am getting huge % difference for all but one of the 5 trials! We are using the acceleration theory equation versus the acceleration experiment. Can anyone help me with this so I don't totally mess up my lab because of my lab partner?

    What exactly were you measuring and are you applying the theory correctly? How are you making the measurements? It's hard to say what kind of errors you will get without some detail.
