One paragraph, so you can see how it reads
PHY203 · UNIT 1 SIMPLE HARMONIC MOTION
If the spring is stretched by pulling the mass longitudinally, due to elasticity a restoring force comes into play which tends to bring the mass back towards the equilibrium position (Fig l.lb). If the spring were compressed the restoring force would tend to extend the spring and restore the mass to its equilibrium position (Fig. l.lc).
