the spring does not have a mechanical adavantage because the amout of force you put in to it is the amoot of force that the spring provides. The real mechanical is that you can time when the force is provided
Springs are great for absorbing energy. The spring force is negative when the spring is stretched and positive when it is compressed or pushed.
a spring balance is used to measure a pushing or pulling force.
How about a spring?There are two kinds of springs, and you can tell the difference by looking at them when they're not under load. We'll call one a pulling spring, and the other a pushing spring. A pulling spring has all the coils touching when it's just laying there; a pushing spring has the coils spread out. I'm calling them what I'm calling them because you load a pulling spring by pulling on it and it pulls to return to its at-rest state, and you load a pushing spring by pushing on it (or "compressing" it) and it pushes to return to rest.If you load a pushing spring, it will contain potential energy equivalent to the load you put on it. Remove the load, and the spring will relax to its at-rest state. If the spring's big enough and you allow it to relax in an uncontrolled fashion, it can do terrible damage--one of the warnings we give mechanics who work on suspension springs is, "if you don't secure the spring while you're releasing the tension, it will take your head off." And it will.

When you compress a spring with a force, you are adding elastic potential energy to it. This can be released and turned back into mechanical energy. There will be some thermal energy produced due to the flexing of the spring material. If the spring is suddenly released there will be kinetic energy formed and the spring will overshoot its rest position, so there will be an interchange of kinetic and elastic energy until the motion is damped out and it comes to rest. Usually as I'm sure you know, there are dampers fitted to absorb the motion and stop oscillations. However if not damped, the spring will go on oscillating until the inherent resistance of the material to being continually strained has had time to act, otherwise we would have perpetual motion! This resistance of the spring material must appear as heat, in the spring itself.
It is potential energy.
