Determining spring constant k The data acquisition process for this part would require a student to record the deflection of the metal ruler from its equilibrium position for various masses attached to the string (watch video). A set of data that you can use for your analysis can be found in Table 1. There is no uncertainty associated with the masses. There is uncertainty in the deflection, which was measured using a standard classroom meter stick like the one shown in Figure 1.
