Which term describes the time it takes for an object to complete one full cycle of motion on a spring? A. period B. frequency C. amplitude D. time E. force

option (A) is correct

Explanation:

The taken to complete one full cycle of motion on a spring is called its period or time period.

It is denoted by T and its SI unit is second.

The number of oscillations completed in one second is called frequency. It is denoted by f and its SI unit is Hertz.

Period is the reciprocal of frequency.

The maximum displacement from its mean position is called amplitude. Its SI unit is metre.

I think it's b) frequency
