Archimedes' principle, 1 of 3. The upward buoyancy force on an object immersed in a fluid is equal to the weight of the displaced fluid (Archimedes' principle). Here, an aluminium block is suspended by an expanded spring and hangs freely in an empty beaker. Water is then added to the beaker and the block becomes submerged. Due to the buoyancy force, the block rises up and the expansion of the spring is reduced. | |
