#static system
- Forceless — Devoid of mechanical force, dynamic energy, or propulsive movement capacity; a physical system or structural element characterized by the absence of active force vectors. This very rare neologism is occasionally used in theoretical works on dynamics or computational physics to describe a state of absolute rest or an inert body that exerts no structural pressure on the environment.
- Astatization — A technical process or structural method through which an oscillating system, a measuring instrument (such as a galvanometer or seismograph), or a regulator is brought into a state of astatism; this operation cancels or minimizes the elastic or gravitational restoring force, causing the system to remain in equilibrium regardless of its position or considerably increasing the device's sensitivity to external perturbations.
