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 distancethat is, F s = kx, where k is a constant factor characteristic of the spring (i.e., its stiffness), and x is small compared to the total possible deformation of the spring. \vec F_s= -k \vec x F s = kx. Where, F s F s = Restoring force in spring (N) = Deformation in spring (m) F = Force applied to spring. How to Calculate a Spring Constant Using Hooke's Law For a mass attached to a spring, the period of oscillation is equal to 2 (m/k). I actually derived the formula of k = 4^2m/T^2 by differentiating the sin(t) function of displacement twice to find the acceleration, then multiply by mass and divide by amplitude to find spring constant. Elastic potential energy is another important concept relating to Hookes law, and it characterizes the energy stored in the spring when its extended or compressed that allows it to impart a restoring force when you release the end. Therefore, F = 5 * 0.4.
