The experiment included a number of components which required us to align things or place things at a certain point along a measuring scale. However, the distance between the measuring scale and the indicator used to obtain the measurement made it extremely subjective as to where to place the indicator. A number of the errors due to parallax fluctuated in both directions and can therefore be labeled random errors.

Unformatted text preview: However, a few key errors occurred in only one direction and can therefore be classified as systematic. <br><br>First of all, the determination of when the indicator disk was within the indicator bracket was always quite subjective. However, since we were looking down at the indicator disk, we almost always got results that favored more force than what was actually being applied to the rotational mass. Secondly, we viewed the rotational mass from the right side for most of the experiment and therefore, the distance between the rotational mass and the poles was smaller than was actually measured during the experiment. Other errors along those lines existed, but these two were by far the most significant in this experiment. Embellished...
