Choose an appropriate scale and plot a Force vs. Displacement graph (that's Force on the y and Displacement on the xvaxis) using your data from the previous step. Calculate the slope of the line created from your data, assuming you took your data correct and the line is fairly straight. A ruler might help. I Slope Calculation: What did you just find by calculating the slope above? (Hint: look at the units) : Calculate the spring constant mathematically using Hooke's Law and your data for the 250 g mass: Spring Constant Calculation: How do your slope and calculated values compare
