## Homework Statement

I know the answer to this question but I just need to know how I can prove this in a laboratory fashion...

Here is the question:

Why doe s a spring continue to vibrate and eventually come to rest when stretched and then released??

It has something to do with calculating efficiency but I dont know how to prove that in a lab.

## Homework Equations

I think you have to use Ee = 1/2 k x^2

F x = +/- k x

## The Attempt at a Solution

I know the answer to the question but I need to verify how I can prove this if asked to do so in a lab

Thanks a lot!!
