As the internal angle increases for squares, penatagons and so forth, the stability decreases.

Thallium is the heaviest member of the Group 13 metals; the stability of group 13 metal hydrides decreases with increasing periodic number.

The stability of AT cut crystals decreases with increasing frequency.

Similarly, if the center of gravity is moved aft, the longitudinal static stability of the aircraft decreases.

Ploughing speeds up erosion because the soil remains uncovered for a long period of time and if it has a low content of organic matter the structural stability of the soil decreases.

High initial stability (ISQ values of 70 and above) tends to not increase with time, even if the high mechanical stability will decrease to be replaced by a developed biological stability.

The long-term stability of hydrogen maser standards decreases because of changes in the cavity's properties over time.

As speed increased, the Lightning's directional stability decreased; there were potentially hazardous consequences in the form of vertical fin failure if yaw was not rapidly counteracted by correct rudder use.

Generally, in terms of mobility versus stability, if mobility increases, stability decreases as follows:

The US now emphasises political stability and the need to decrease the size of Central America's military machines.
