Calculation of free fall g

  1. Feb 28, 2009 #1
    1. The problem statement, all variables and given/known data

    Determine the value of 'g'

    2. Relevant equations
    Anything


    3. The attempt at a solution
    I only know of the pendulum method.
    Can someone please show me of other methods to calculate g without the use of fancy equipment such as a picoscope.

    The pendulum method is generally the most elementary method that gives a reasonably accurate result quite easily.

    Another method is to drop a ball from a known height, h meters, and to measure the time it takes to fall to the ground. By elementary equations of motion, we find

    [tex]s= 1/2 gt^2[/tex] and hence we can easily determine a value of g from this.

    Be sure to minimize air resistance for a decent result.
