Science 21


Two students were investigating the effects of different forces applied to springs.

Experiment 1

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.

Experiment 2

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.
