Hook investigated the relationship between Force and the extension of a spring's distance. He found that when too large a force was applied to the spring, it no longer returned to its original position. It was stretched beyond its elastic limit.

The standard apparatus for Hook's Law is supplied in this simulation. There are 100 springs which may be selected in random order. It is suggested that the student work with 2 or 3 springs to get a feel for the experiment and use their mathematical skills in calculating slopes.

The student collects 10 sets of data for Force and Distance. A plot of Force vs Distance is made. The equation of the graph is then determined using

                      F = md + b where m = slope of the graph

The slope represents the Spring Constant. The student is then asked to calculate the % error for the experiment using the Spring Constant Tables to find the actual value of the spring used.
