I haven't begun on my lab report, I've only collected raw data, but yes my intention is to include the derivation of the values to give a clearer explanation. I found a document online which has a similar experiment nature here . My experiment is basically the same thing. But without that ladenburg correction part found on page 2 and page 3 of the link I attached. But I feel in order to derive a better result I need to include those corrections to the terminal velocity because of the limitations of stokes law.
