When an object moves to and fro or back and forth along the same line, it is called a simple harmonic motion(SHM). This motion is used to model many real life-situations in our daily life.
Let us look at a few of them:
Swings that we see in the park is an example of simple harmonic motion. The back and forth, repetitive movements of the swing against the restoring force is the simple harmonic motion.
The pendulum oscillating back and forth from the mean position is an example of simple harmonic motion.
- Bungee Jumping
Bungee Jumping is an example of simple harmonic motion. The jumper oscillating up and down is undergoing SHM due to the elasticity of the bungee cord.
The back and forth movement of the cradle is caused due to a single push and is maintained by the principle of SHM, and hence, causing the baby to sleep.
The process of hearing is impossiblewithout simple harmonic motion. The soundwaves that enter our ear causes the eardrum to vibrate back and forth.
