[This question concerns a pendulum]
The table below shows the positions of the bob for five consecutive flashes of the strobe light
This is the incomplete form of the question, because all I want to know is how to identify the angle.
I know the zero angle position. My question is: the +9 angle, is that measured to the right of zero? or to the left of zero? and how do you decide that?
Thank you
