Spring Forces FRQ Set
Write a complete response before opening the reasoning guide. The four prompts deliberately use different response modes.
A spring with k = 160 N/m is compressed 0.075 m from its relaxed length. Determine the spring force on an attached cart, including direction if +x is the compression direction.
Reasoning and scoring guide
F_s = −kx = −(160)(0.075) = −12 N. The negative sign means the spring force points opposite the +x compression, toward equilibrium.
Describe the ideal graph of spring force F_s versus displacement x and explain the physical meaning of its slope and origin crossing.
Reasoning and scoring guide
The graph is a straight line through the origin with slope −k. The origin means zero displacement gives zero spring force; the negative slope represents restoring direction.
Design a static experiment to determine an unknown spring constant using known hanging masses. Identify a graph whose slope gives k.
Reasoning and scoring guide
Hang known masses, allow equilibrium, measure extension x, and calculate applied force mg. Plot force magnitude versus extension; slope gives k. Repeat and stay within the Hooke’s-law region.
Two springs are stretched by the same distance, but spring A has twice the spring constant of spring B. Compare the force magnitudes and explain what “stiffer” means quantitatively.
Reasoning and scoring guide
|F_A| = k_A|x| = 2k_B|x| = 2|F_B|. A larger k means more restoring force is required/produced per unit displacement.
