1. Find the %difference between your experimental result for g
and the accepted value of 9.81 m/s2 .
2. Looking at your plot, did the data points fall near the
straight line fit calculated by the program? Explain in terms of
what you expected.
3. Hopefully you obtained a good value for g in this experiment.
In fact, this is one of the best ways to determine g since it is
unnecessary to calculate the acceleration directly. But, can you
think of any effects that might have contributed to not getting the
accurate value of 9.81 m/s2 that we expected
