Question : Which of the following is an example of simple harmonic motion?
Option 1: Earth spinning on its axis.
Option 2: Simple pendulum motion.
Option 3: Ball bouncing on floor.
Option 4: Motion of a ceiling fan
Correct Answer: Simple pendulum motion.
Solution : The correct option is Simple Pendulum motion .
Simple harmonic motion is exemplified by pendulum motion. Simple harmonic motion happens when an item is subjected to a restoring force that is proportional to its displacement from a fixed point.
The restoring force in the case of a simple pendulum is provided by gravity. Gravity tries to reposition a pendulum when it is moved from its equilibrium position, which is the vertical hanging position. A sinusoidal motion results from this.
