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| | | |

0.09| 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...
