I'm studying the principles of accelerometer and given below is what is stated in [LiveScience](https://www.livescience.com/40102-accelerometers.html)

>An accelerometer is an electromechanical device used to measure acceleration forces. Such forces may be static, like the continuous force of gravity or, as is the case with many mobile devices, dynamic to sense movement or vibrations. Acceleration is the measurement of the change in velocity, or speed divided by time.

So it says that it measures acceleration forces due to a static force, but how can a static force induce an acceleration on an object because **a static force virtually keeps an object at rest**.

An object at rest does not have an acceleration does it?
