Suppose that the original spring of a heavy object is elongated L. when it is cut to half the length, the spring's elongated length becomes half of the original length, that is, L / 2. Because the weight of the heavy object below remains unchanged, according to Hooke's law f = KX, if f remains unchanged and X becomes 1 / 2, then K becomes 2K. When two springs are combined to form a new spring, the force originally borne by one spring shows that
