Using the "Energy" simulation, find the relationship between stored (potential) energy in the spring and displacement of the end of the spring. Use the ruler to make bar graph measurments and also use the ruler to measure the displacement from the natural length at any moment when the simulation is paused. Make sure that the damping slider control is set at zero (all the way to the left). The default setting for damping in this energy simulation is not zero. So, slide it all the way to the left before you begin. Again, does the relationship show a linear, quadratic, trigonometric, or other nature? How does the spring constant figure into this relationship
