Unstable balance vs. not

https://en.wikipedia.org/wiki/Stability_theory

The classic example is a pendulum with a solid rod (instead of a string) which has a stable balance point at the bottom of its swing, where if you move the pendulum slightly it will swing back towards that balanced state. However, theoretically the pendulum can also be balanced pointing directly up. In this case, if you move the pendulum slightly it will swing down away from that upwards balanced state.

Position-dependent Bongard Problems vs. position-independent visual Bongard Problems.

Left examples have the keyword "pos" on the OEBP.

If applying a translation to the whole of any example can change its sorting the BP fits on the left side here.

For a BP to be a left example here it must not only relate to position, but furthermore absolute position (not just position of things relative to one another) in its examples must be essential to parse the solution.

Note that BPs about comparing relative position between multiple things in one example fit on the right side.
