Law of Archimedes: The buoyant force is equal to the weight of the replaced liquid or gas. |
|
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 with 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. An acceleration due to gravity was presupposed
by If you see the words "Maximum exceeded!" (red letters), you have to choose an adequate measuring range. |
