How an Accelerometer Works. Accelerometers are electromechanical devices that sense either static or dynamic forces of acceleration. Static forces include gravity, while dynamic forces can include vibrations and movement. Accelerometers can measure acceleration on one, two, or three axes.
For example, an accelerometer at rest on the surface of the Earth will measure an acceleration due to Earth's gravity, straight upwards (by definition) of g â 9.81 m/s 2. By contrast, accelerometers in free fall (falling toward the center of the Earth at a rate of about 9.81 m/s 2) will measure zero.
