button. How does the force of gravity compare to the spring force? Is the system in equilibrium? [1 pt] 2. Using the ruler, measure how far the mass stretches the spring. Should you measure from the center of the mass or from the bottom of the spring? [2 pt] 3. Using Newton's second law in equilibrium and the weight of the mass, calculate the spring constant. Remember to convert your numbers to the correct units. [2 pt] 4. This is just one number though. One of the best ways to find the spring constant is to use many masses and plot the weight vs displacement, as shown below. From the plot, what value gives the spring constant? How does this value compare with your single point calculation? [1 pt]
