Question

Define a non-periodic change. Is the swinging of a pendulum a non-periodic change?

Answer 1

1. Changes that are not repeated at regular intervals and occur irregularly are called non-periodic changes.
2. These changes can occur at any time and they do not have any periodicity. Examples of non-periodic changes are landslides, earthquakes, power breaks down, etc.
3. No, swinging of the pendulum is not a non-periodic change because the motion of the pendulum is repeated at regular intervals of time. That's why the swinging of the pendulum is a periodic change.
