Experiment with angular acceleration

  1. Dec 8, 2011 #1
    I'm not sure if this goes in there since it's a question about an experiment involving classical mechanics.
    So I've done an experiment where I have determined for a rotating cylinder, its angular acceleration as I let a weight attached to it drop. Now each of these angular accelerations have an uncertainty, and I want to figure out the best estimation for the angular acceleration. What I did was to make an average over the angular acceleration weighted over their uncertainties. This is correct right? - I'm pretty sure, that's how it's done.
    My problem is however, that I now don't know how to figure out the uncertainty for this estimated angular acceleration - how do I do that?

    After this, I don't know what your explanation(s) means.
