Cork Bob Accelerometer

A cork is suspended from a string attached to a rubber stopper inside an inverted water-filled flask. The forces acting on the cork are the buoyant force (provided by the water, whether at rest or accelerating), gravity, and the tension in the string. When the system is accelerated, there is an additional component of the buoyancy force in the direction of the acceleration. Since the cork is not accelerating with respect to the water, the net buoyancy force must be balanced by the tension in the string. Thus the cork leans in the direction of the acceleration.
