Two students were investigating the effects of different forces applied to springs.
A mass, M, was hung from a spring, raised to position A and released. The mass is allowed to hang freely, and oscillates (swings) between positions A and C until an equilibrium (motionless) state is reached at position B. Figure 1 shows the students’ set up, as described.
The students repeated Experiment 1 but tried using springs of different material and varied the mass of the weight. Figure 2 shows the elongation of two springs, A and B, with various weights attached.

According to the passage, which of the following best explains why equilibrium was reached at position B in Experiment 1?CorrectIncorrect
According to Figure 2, when a force of 2N was applied to spring B, by which amount did the spring elongate?CorrectIncorrect
Based on the information provided, it can be inferred that after the mass was released in Experiment 1, the spring oscillated becauseCorrectIncorrect
The students claim that at any applied force, spring A will always elongate more than spring B. Based on Figure 2, is their claim correct?CorrectIncorrect
The students collected additional data, but forgot to label which spring was used in each trial. At forces .8 N and 1.4 N they measured an elongation of .055 m and .092 m, respectively. Based on this information and Figure 1, which spring were the students most likely using?CorrectIncorrect
