G by free fall experimental error

  1. Sep 20, 2012 #1
    This isn't so much a H/W question, but we have 2 sets of values,

    TMax and Tmin.

    Δ is the difference between them.

    We are told to get Δ/2 and get the %uncertainty of this.

    Why do we halve Δ?

    If you choose a value right in the middle of your max and min values, then you can say that the max value differs by Δ/2, and the min also differs by Δ/2. So Δ/2 could be considered sort of a maximum error value.
