The Phidget VINT Accelerometer measures up to ±8g (or 78.5 m/s²) in each axis, which is more than you'll ever produce in most ordinary applications. The MOT1100 connects to a port on a VINT Hub. The most common use for an accelerometer is to measure the movement of an object, such as a person or robotic vehicle.
You can compare the acceleration values on each axis to determine the direction and strength of the acceleration, and in some situations, even estimate velocity and position. An accelerometer could also be used to detect vibration.
