Observations on energy transformations

We had many opportunities to go for walks, often to playgrounds. Neil likes swings and really really likes slides. Miekie and Pieter like roundabouts most. Marisa and I serve mostly as sources of energy that, once steady states have been reached, compensate for frictional losses in the hinges of swings and aerodynamic drag losses. We also increase the potential energy of Neil at a frequency of about once a minute while at the slide, enabling him to transform this into kinetic energy with the help of the slide. However, we act as lateral stability controls and descent-velocity controls too, expending more of our own energy this way, but still finding it strangely relaxing.

While providing greater stability, the four chains make movement a little more restrictive
