1. The problem statement, all variables and given/known data We did a pendulum lab and found Q then we were asked to find K from that. The professor gave us a formula K= 4pi2/m2 where m was the slope of a line on a graph of our periods vs lengthQ then stated it should be number we would recognize. I assumed maybe we were going to calculate g, as this is something I have done before but I thought K was a spring constant from Hookes law. What am I trying to find. 2. Relevant equations g=Lpi2/T2 3. The attempt at a solution The data is relative but I did get some answers around 9.77, close enough to 9.8 considering the human error involved.
