ELASTIC FORCES and HOOKE’S LAW 1. Objective The objective of this lab is to show that the response of a spring when an external agent changes its equilibrium length by x can be described by Hooke’s Law, F. = -kx. Here F is the restoring force or the force exerted by the spring on the external agent and k is a
