Purpose:Illustrate the behavior of a liquid accelerometer accelerating down an inclined plane.
Description:When the liquid accelerometer is accelerated, as in the case of the photograph at the left above, the liquid moves in the direction opposite to the acceleration, because of its inertia. When it is held motionless on an incline, the liquid moves toward the downhill side. When the accelerometer is allowed to accelerate down the incline, it will line up with the surface of the water parallel to the inclined plane.
