  • If we plot a graph between force applied and the displacement then work done can be obtained by finding the area under the F-s graph.
  • If a spring is stretched or compressed by a small distance from its unstretched configuration, the spring will exert a force on the block given by
    F = -kx, where x is compression or elongation in spring, k is a constant called ‘spring constant’ whose value depends inversely on unstretched length and the nature of material of spring.
  • The negative sign indicates that the direction of the spring force is opposite to x, the displacement of the free-end.
