Buoyant Force in Liquids

English Deutsch Français Italiano
English Deutsch Français Italiano

This Java applet shows a simple experiment concerning the buoyance in a liquid: A solid body hanging at a spring balance is dipped into a liquid (by dragging the mouse!). In this case the measured force which is equal to the difference of weight and buoyant force is reduced.

You can change (within certain limits) the preselected values of base area, height and densities by using the appropriate text fields. After you have pressed the "Enter" key, the program indicates the new values of depth, replaced volume, buoyant force, weight and measured force. A gravitational acceleration of  g = 9.81 m/s2 was presupposed.

If you see the words "Maximum exceeded!" (red letters), you have to choose an adequate measuring range.

Law of Archimedes: The buoyant force is equal to the weight of the replaced liquid or gas.
