Physics Lab Tutorials
Often, laboratory experiments are designed to determine the value of
well-known physical quantities such as the value of
p or the acceleration due to earth's
gravity, g. Since these quantities have
accepted or true values, we can calculate the
percent error between our measurement of the value and the
accepted value with the formula
Sometimes, we will compare the results of two measurements of the same
quantity. For instance, we may use two different methods to determine the
speed of a rolling body. In this case, since there is not one
accepted value for the speed of a rolling body, we will use the
percent difference to determine the similarity of the measurements.
This is found by dividing the absolute difference of the two
measured values by their average, or
