In this lab, students investigated oscillatory motion of a mass at different specified angles. The mass was displaced at 5˚ and 45˚ respectively. The average of 3 trials with 7 oscillations were taken, at 8 different lengths. The results were graphed, and the data was analyzed using the LINEST statistical function. The g value was determined; using this score, the T-score value of the data was determined. 1. The graph of the 5˚ and 45˚ angles were similar to one another per each drop length. The graphs should look the same. The calculated g value of 8.53 m/s2 was similar to the gravitational free-fall acceleration constant of 9.8 m/s2 2. The high T score of 13.5 indicates that the agreement is unacceptable, and sources of systematic error can be further explored.3. Some errors included not being able to release the mass at the specified angle consistently each time. Discerning the exact angle was difficult to the naked eye. When using the stopwatch timer, there was a small lag in time between the recorded time of the results. 4. If a heavier mass was used, then the time taken to complete one oscillation would take longer. The graphed results would still be similar to one another, since the same mass would be used per each angle.
