Physics A | 1.4 Assignment: Hooke’s Law Lab Learning Objectives: ● Identify a relationship as direct or inverse by looking at a graph. ● Identify which variable goes on the x-axis of a graph. ● Identify which variable goes on the y-axis of a graph. ● Write an equation from a proportion. ● Using a graph, estimate values from an experimentally determined relationship using interpolation and extrapolation. The end goal of the lab is to measure the stretch of springs. You will then calculate the force exerted on the spring and graph. Spring constant to use for this lab is: 0.33 N/cm Data table: (5 points) Mass (g) Force (weight) exerted (N) Spring Constant (N/cm) Stretch (cm) 0 0 0.33 0 2 0 0.20 0.33 0.61 6 0 0.0588 0.33 0.18 10 0 0.98 0.33 0.30 16 0 0.1568 0.33 0.48 20 0 0.196 0.33 0.59 24 0 0.2352 0.33 0.71 1. Calculate mass to weight. Remember to rearrange to form a question shown below a. ? N = 20 g x 1 kg 1000 g x 9.8 N 1 kg = 0.20 N mass equals weight divided by the acceleration of gravity (M+ W/G) so this is 20N 2. Fill out the stretch part of the data table above by using the relationship that Force = spring constant * stretch. 3. Graphing setup (4pts) a. Label the x-axis with the ______ variable.
