EXPERIMENT: Hooke's Law
Questions: A. How does the relative stiffness of a spring relate to its spring constant? B. How does PE change relative to the stretch of the spring? C. Indicate on your graph for the rubber band where the linear behavior stops. What does this mean? D. Which is stronger in the region where Hooke's law is obeyed, the spring or the rubber band? Explain. E. Explain what happens to the "spring constant" of the rubber band for the non-linear part of your curve.
