Question

Give two examples of periodic changes.

Answer 1

Periodic Changes:

• The changes which occur within a regular interval of time are called periodic changes.
• These changes tend to repeat or reoccur themselves at the same interval of time periodically.
• Examples involved are the swinging of a pendulum, the clock striking an hour, the rising and setting of the Sun, the change of seasons, etc.

Hence, two examples of periodic changes are:

1. The clock striking an hour
2. The change of seasons.
