Abstract
Intent: To conduct an experiment to prove the yielding support distance is directly proportional to the period.

Results:
d(m)| Time for 20 Oscillations (s)| Time for 1 Oscillation T (s)| T2(s2)| d3(m2) x 10-3| | 1| 2| 3| Average| | | |
0.24| 31.50| 31.47| 31.44| 31.47| 1.57| 2.46| 13.8| 0.21| 31.0| 30.97| 31.09| 31.02| 1.55| 2.41| 9.2|
0.l8| 30.56| 30.69| 30.69| 30.65| 1.53| 2.35| 5.8|

0.12| 30.16| 30.19| 30.22| 30.19| 1.51| 2.28| 1.7|
0.09| 30.00| 30.00| 29.96| 29.99| 1.50| 2.25| 0.7|

Interpretation: The lab was a success because it was proven that as length was of the length of the yielding support decreased, the period also decreased. A cause of error was due to human reaction time. Although 20 oscillations were counted, the person holding the stopwatch might have stopped milliseconds before or...
