The characteristic of sound that depends on how much force is used to make an object vibrate is amplitude.

Here's why:

* Amplitude refers to the maximum displacement of a vibrating object from its resting position.

* When you apply more force to an object, you cause it to vibrate with a larger amplitude.

* Larger amplitude vibrations create sound waves with greater pressure variations, resulting in a louder sound.

So, the more force you use to make an object vibrate, the greater the amplitude of the vibrations, and the louder the sound will be.
