The acceleration g due to gravity is measured in two experiments. In the first experiment, the value of g was measured to be 9.85 m/s2. In the second experiment, g was 9.70 m/s2. Find the percent difference of the measurements, the percent error of each measurement, and the percent error of their mean if the accepted value of g is 9.8 m/s2. Compare the experimental value of g from the accepted value of 9.8 m/s2. Calculate the percent error.
