Abstract The main purpose of this laboratory experiment is to study simple harmonic motion (SHM) and to use the pendulum to experimentally calculate g (acceleration due to gravity, 9.8 m/s 2 . Students will learn how to use a simple pendulum. The time taken for 20 cycles will be measured twice at different lengths. The average will then be calculated and used to calculate the period, T. This experimental period and the predetermined length of the pendulum will be used to create a graph. The graph of T 2 vs. L will yield a slope equal to 4π 2 /g. From this slope, a value for g experimental can be calculated. The percent error between g actual and g experimental will then be calculated. The value for slope was determined to be 3.75 s 2 /m. From this slope, the value for g experimental was calculated to be 10.5 m/s 2 . The percent error between g actual and g experimental was calculated to be 7.42%.
