1. Using the "Intro" simulation, find the relationship between spring force and displacement of the end of the spring. That is, does the relationship show a linear, quadratic, trigonometric, or other nature? The spring force will match the weight of the object hanging on it when the system is in equilibrium.The natural length and the equilibrium position controls should be checked so that you can measure the equilibrium displacement with the ruler. How does the spring constant figure into this relationship
