Precision during free-fall experiments.

  1. Sep 14, 2009 #1
    I'm not sure how to answer this question, so I'm turning to you guys for help.

    The question, specifically, is: "When timing the fall of a ball, how would you achieve greater precision, with larger or smaller heights?"

    Any help would you appreciated.

    Mathematically, in larger heights. It's all about relative error (which is the mathematical expression for precision). Imagine you have a timer that measures untill 0.01 seconds then the greater the time you get is the smaller the % of it it will be 0.01.

    Just tell if you don't see it ;)
