At the Active Figures link at you can move the object to new positions as well as change the density of the object to see the results.

7. Active Figure An object floating on the surface of a fluid experiences two forces, the gravitational force Fg and the buoyant force B. Because the object floats in equilibrium, B = Fg. At the Animated Figures link at you can change the densities of the object and the fluid.

Figure 14.22  Streamline flow around a moving airplane wing. The air approaching from the right is deflected downward by the wing. By Newton’s third law, this must coincide with an upward force on the wing from the air—lift. Because of air resistance, there is also a force opposite the velocity of the wing—drag.
