The Simple Pendulum - Lab Report Example 1.79 seconds) as compared to 1.66 seconds in the second case. This can be explained using the formula:; where T is the period, L is the length, and g is force of gravity. T and L are directly proportional (Wilson 39). The â€Å"T† values for the 81 cm long simple pendulum of table 1 are more or less similar to the â€Å"T† values of the 81 cm long pendulum of table 2. For table 1, the average period is 1.77 seconds and for table 2 is 1.79 seconds. However, the error margin in table 2 is significantly bigger. The same results can be seen when comparison is done using 61 cm long simple pendulum and taking into account the error margin. This results explained by the fact that regardless of the size of the mass, the pull of gravity, which is also the driving force, remains the same. Acceleration for the two different masses also remains the same resulting to the similar period. In other words, the size of the mass has no effect on the period of a simple pendulum (Wilson
