Unformatted text preview: BUOYANT FORCE - ARCHIMEDE'S PRINCIPLE When a rigid object is submerged in a fluid (completely or partially), there exits an upward force on the object that is equal to the weight of the fluid that is displaced by the object. Explanation: When the object is removed, the volume that the object occupied will fill with fluid. This volume of fluid must be supported by the pressure of the surrounding liquid since a fluid can not support itself. When no object is present, the net upward force on this volume of fluid must equal to its weight, i.e. the weight of the fluid displaced. When the object is present, this same upward force will act on the object. The net force on the object is given by, * When the density of the object is less than that of the fluid, the net force will be upwards and the object will rise. A Helium filled balloon is a good example. QT Movie Demonstration of Archimedes' Principle (2.3M) Floating Objects: When an object is floating, the net force on it will be zero. This happens when the volume of the object When an object is floating, the net force on it will be zero....
