A physics class could go deeper into the meaning of this theorem. Students can now plot these data pairs. After students have done several experiments, they should be asked to explain some of their results. For example, from the above plot, they should see that as the weight goes farther away from the fulcrum, more spring force is needed in order to balance the arm of the number balance. So far in this activity, Fw has remained constant.
Students can further experiment by changing the weight.
Weights of different amounts should be given to the students for experimentation. They can first experiment with a stationary weight and spring balance, and then again by changing the location of the weight or spring balance. For each experiment, data points should be plotted and conjectures should be made. References National Council of Teachers of Mathematics.
