Pendulum Lab

Kai Assoun
Pendulum Lab
When a Pendulum is swinging, the length of this pendulum has a certain time attributed to each swing. When the length of a pendulum is shortened,  the time it takes to complete a full swing is shortened.
When the length is increased,  the time it takes to complete a full swing of the pendulum increases. 

I began the experiment of the pendulum with a length of 225cm and timed it with a stopwatch.  I progressively shortened the pendulum's length and timed it at each length to test the theory that the swing time would shorten as the pendulum shortened.  I swung the pendulum 7 times at 7different lengths and timed each one.



The pendulum's starting length of 225cm gave the pendulum a full swing of 3.034 seconds.
I then shortened the pendulum to 202cm and the time it took to make a full swing was 2.982 seconds, which was 0.052 seconds shorter. For each following swing as the the pendulum was shortened the full swing time was shortened.

The length of the pendulum directly influences the time in which it takes for the pendulum to make a full swing.
