When a spring vibrates, it does so with a steady pattern. The time it takes to complete One cycle of this vibration is known as the ___ of the spring.

Period of vibration

Explanation:

The period of vibration of the spring is defined as the time taken by the spring to complete one complete cycle of motion. One complete cycle of motion involves stretching and returning of spring to its original position.

The frequency of motion is defined as the number of cycles completed in one unit time.

Thus period has a inverse relationship with frequency of the spring and is represented as
