Results and Discussion: Results for Spring 2 and Spring 3 did not turn out very well. There was an error in the readings when the tests were performed. Luckily, data for Spring 1 with and without the damper turned out to yield good results. The spring constants were calculated to be 5302.7 N/m for spring 1, 1656.2 N/m for spring 2, and 675.2 N/m for spring 3. This makes sense because the stiffness of the spring depends on the thickness of the spring. Spring 3 was the thinnest spring and spring 1 was the thickest spring used in the lab. Since the data obtained for Spring 2 and Spring 3 was not very good, the results are included using data obtained for Spring 1. The free response of the system with spring 1 connected was plotted using different masses. The trend between natural frequency and mass of the system is that the natural frequency decreases exponentially as mass is increased. This means that the system will oscillate slower because there is more mass. The experimental natural frequency was actually found to be slightly higher than the theoretical natural frequency. This is most likely because the values calculated for the theoretical natural frequency are based on an ideal system. In reality, no system is exactly “ideal”. There is still some damping due to friction between the rod and the slide. Although the values are different, the trends are the same for the theoretical and the
