In this modeling activity, students examine the spring-mass-dashpot that is part of a car suspension. We model a "quarter car'', meaning a single wheel, and compare effects of different masses, spring constants, damping coefficients, and the angle at which the assembly is installed. Students familiar with second order linear homogeneous ordinary differential equations can go straight to the modeling activity. We provide a preliminary activity to learn or review the basics of this background, and we provide the answers for students to the optional background activity.
