Unseen Prac (1 Viewer)

Hello people, so, I have an unseen prac tomorrow. I am pretty bad with pracs. The notification for the prac read calculating g. This means we probably are gonna the pendulum experiment. The thing is, I am pretty bad at the questions to improve the experiment and sources of errors. How would you do them?

repeat multiple times

Could I say that the rotational momentum induced in the pendulum, is a source of error?

Yeah, I wrote down repetition in my phy prac but my teacher told me to specify and gave me no marks. And I didn't really get as to how to "specify"
