Question

The vibrations of a simple pendulum are also known as _________.

Answer 1

1. A pendulum can be formed by suspending a ball with a string.
2. When we move the ball from its original position, it executes to and fro motion.
3. This to and fro motion is periodic as it keeps on repeating.
4. This periodic to and fro motion is called oscillation.
5. Therefore, the vibrations of a simple pendulum are also known as oscillations.
