Part III: SHM-Spring-mass Introduction The objectives of this lab are to study simple harmonic motion (SHM) in a spring-mass system. to study the relationship between period and mass in this SHM. to verify the spring constant we determined for the spring we used the previous lab. In the last section lab we did experimentally determined the spring constant applying Hook's law which was about . In this lab we will verify that our result is indeed correct by analyzing the period of a simple harmonic oscillator for a spring mass system. To open the simulation for this virtual lab CLICK HERE. You will see the same simulation window that we used last time (see Fig. 1). Click on "Lab" window and it will lead you the same window Figure. 1 we used (see Fig. 1). Figure. 2 Part I: Collecting the data 1. Check the box for "Mass Equilibrium" and hang the 100g mass at the end of the spring and reduce the mass to 50g. As you saw in the previous lab the mass comes to rest eventually due to damping. Once the mass comes to rest stop the simulation and set the damping to zero. Draw a free-body
