3-2 Click reset and choose a mass and length. Select Planet X as the planet. Using an angle less than or equal to 15 degrees, measure the period of the motion. You may want to make multiple trials if simply using the stopwatch. Now using equation 14.27 determine the local acceleration of gravity on Planet X. Show your work below. "g" on Planet X = m/s2 3-3 If you were actually performing this pendulum experiment in a lab, there would be friction in the system. Repeat the experiment on Earth with friction turned to LOTS. Does the inclusion of friction significantly change your results
