All objects, the accelerometer included, experience a constant downwards acceleration of 1G due to gravity. Most accelerometers measure acceleration in multiple axes. By measuring the acceleration caused by gravity in each axis, and performing some trig, you can figure out the orientation of the accelerometer.
