Experiment #6 Lab Worksheet
1. Cut and paste the F(x) plots from the a) spring and b)
elastic band into the frame below. Each figure should be
about 7 cm on a side such that both fit on the same line.
Use “a)” and “b)” to label them.
2.
Write a figure caption for the plots. You could, for example, mention whether or not the data
are linear or nonlinear, hysteretic or nonhysteretic, how any hysteresis is interpreted, what
happens to any nonconserved energy, and what the spring constant is or what the range of
spring constants are.
3. Calculate the potential energy stored in the spring as it was stretched from the lowest to
highest recorded extension. What was the amount of energy released as the spring was unloaded?
Similarly, estimate the potential energy stored in the band as it was loaded with weights, and
estimate the amount of energy regained as it was unloaded. As usual, show your work.
