Part 2: Acceleration Due to Gravity with Varying Heights. 1) Using the second free-fall apparatus, place the metal ball in the release mechanism. It should be over a meter above the receptor pad. Perform a test run to confirm that the ball will hit the pad once dropped. Rele mechani Thumb NEW Dowel 2) Place the ball back in the release mechanism and measure the distance from the bottom of the ball to the receptor pad. 3) Confirm that the Smart Timer is in Stopwatch mode (reset it if necessary). Press Start once the ball is now ready to be dropped. Release the ball by loosening the thumbscrew on the release mechanism. Record the time. The time should be around 0.5s. If the timer indicates a time of a few one-hundredths of a second, something went wrong. Surat 3) Perform another two runs to get an average time. 4) Lower the release mechanism by 10 or 15 cm, insert the ball, and remeasure the vertical distance. 5) Perform three runs and determine an average time. 6) Continue step 4 and 5 until an overall of four different heights are used. 7) For the last two columns of the data table, multiply the distance dropped by two and square the average times. These will be used to construct a linear graph on the graph paper provided at the end of the lab. 8) Granh 2y ys. . Create a proper graph using techniques from the Graphing lab. Determine the value of gravity from the graph and find the percent error between this measured value and the actual value for gravity. % error = Calculations:
