Abstract

Resource Image In this lab students will collect data on their spring mass systems and compare their empirical models to their theoretical ones—giving them an opportunity to actually test a model against data.

Description

Before this lab, students should have modeled spring-mass systems and solved second-order linear differential equations with constant coefficients. The lab will take one 50-minute class period with some outside student preparation to be finished before lab day.  Upon completion of this activity, you may ask your students to turn in a written report with their answers to the questions found in the Student Version of this Modeling Scenario.

Picture setting the spring with single mass hanging from it in motion by displacing the mass a certain distance from equilibrium and letting go.  In this lab, your group will set up your own spring-mass system and collect data on the motion of your system.   You will solve your systems theoretically, and your software will also create empirical solutions using your data.  Your group will compare and contrast your theoretical solutions with the empirical ones.
