They were also given a set of weights, and asked to observe a mass-spring system and graph their results. The graphs from each of the groups are shown below. Compare group 2-5’s graphs with Group 1’s graph. In each case there is one difference between the two observations. The difference may be attributed to a physical parameter of the experiment

Please give both a qualitative answer (describe what changed, either with parameter, equipment or procedure) and quantify the change using the parameters in the equations below. Group 1 used a mass of m 1 . They timed 50 consecutive cycles to calculate the period with a fair degree of accuracy. Then, they started their stopwatch at 3:00:00.0 PM PST. This graph is their result. Identify from each graph what was different about the group’s experiment and explain how you know: Group 2: Group 3: Group 4: Group 5:...
