Spring Elasticity or Hooke's Law

In physics, Hooke's law is an empirical law which states that the force (F) needed to extend or compress a spring by some distance (x) scales linearly with respect to that distance.

$$F_{s} = -kx$$


\(F_{s}\)ā€” the force applied to the spring;
kā€” the spring constant (a measure of the stiffness of the spring);
xā€” the displacement from the equilibrium position.
