Introduction In this lab we will measure the static behavior (stretch vs. force) of simple springs, practice linear fits to find the static spring constant, then make an oscillator and test the relationship between frequency and mass to get the dynamic spring constant. Springs, like those in your car's suspension, or between atoms in solids, are important because they produce simple harmonic oscillator motion (SHM), which occurs throughout all of physics and electrical and mechanical engineeri...
