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.
$$F_{s} = -kx$$
where,
\(F_{s}\)— the force applied to the spring;
k— the spring constant (a measure of the stiffness of the spring);
x— the displacement from the equilibrium position.
