I'm writing a prac report, and I just need something clarified.
The experiment was different masses were attached on a hanging spring, then it had to be pulled down a certain distance, then find the period by finding the time fo each oscillation for each mass. The problem is that when I did the experiment, i didn't pull the down the spring the same distance for each mass. And my calculations for the spring constant using Hooke's Law (the slope of the graph of T vs sqrt M) turned out to be 60 N/m, while many other people got 13-14 N/m. Could this have been due to the different distances pulled for each mass?
