Error Analysis: 1. Using the known value for the acceleration due to gravity, 9.8 m/s2, calculate the percentage error for your experimental value of the acceleration due to gravity, gexp. 2. Because you have performed this experiment using a simulation, your percentage error should be zero, because the correct value of g was programmed in. What sources of error could cause you to have a non-zero percentage error in this experiment? Remember to state if the source of error is random or systematic. 3. In the hands-on version of the lab, a pendulum is constructed using string, rods, clamps, and hanging masses. (See image). What would be some possible sources of error (random or systematic) in this experiment?
