The environment in which we live is full of constant changes. Changes in the weather, humans (human growth), or any other living or non-living thing are all examples. It’s similar to the transformation of any substance or item from one form to another.
Changes that occur regularly or regularly are referred to as periodic changes. Seasonal changes, for example. Day and night, changing phases of the moon, heartbeat, and a clock striking an hour are all examples of periodic motion, whereas water freezing, matchsticks burning, and other non-periodic changes are non-periodic changes.
