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
Chapter 3 forces & newton's law of motion. 3.1 The concepts of force and mass. Newton's second law When a net external force SF acts on an object of mass m, the acceleration a that results is directly proportional to the net force and inversely proportional to the mass.
