This physlet shows a typical Simple Harmonic Motion (SHM) of a mass-spring system.
Drag the block to a stretch (or compress) the spring and click play button. You will see that the motion of this block is periodic and furthermore its displacement from equilibriun as a function of time varies sinusoidally as shown in the graph below. Any motion that repeats itself with a certain period is called periodic or harmonic motion.
