This chapter looks at the deceptively simple world of pendulums. First we cover why pendulums swing back and forth as they do, and tie this into the general idea of simple harmonic motion—a type of oscillatory motion in which a system stores energy (in a spring or by working against gravity) and then uses that stored energy to move back to its original position.
Some of the experiments in this chapter are classic high school or undergraduate physics demonstrations, and in some cases would benefit from non-3D-printed parts. However, ...
