Once we have the spring constant k and the extension x, we can use the formula for elastic potential energy to calculate the energy stored in the spring: EPE = 0.5 × k × x^2. For example, if we have a spring with a spring constant of 80 N/m that is extended by 1.5 m, the energy stored in the spring would be: EPE = 0.5 × 80 N/m × (1.5
Springs function as energy storage devices, increasing their force linearly under compression, extension, or twisting—known as "loading." Hooke''s law explains this behavior: the force (F) exerted by a spring is directly proportional to its displacement (X), expressed as F = -kX, where k is the spring constant indicating stiffness.
