Hooke's law
empirical physical law of mechanics that the force on a spring is proportional to its displacement
AI overview
Hooke's law states that when you push or pull on a spring, the force required is directly proportional to how far you stretch or compress it—meaning twice the stretch requires twice the force. This principle is fundamental to understanding how springs work and forms the basis for many mechanical devices and scientific instruments we use today.

Hooke's law: the force is proportional to the extension Bourdon tubes are based on Hooke's law. The force created by gas pressure inside the coiled metal tube above unwinds it by an amount proportional to the pressure. The balance wheel at the core of many mechanical clocks and watches depends on Hooke's law. Since the torque generated by the coiled spring is proportional to the angle turned by the wheel, its oscillations have a nearly constant period.
