I was just a bit confused about Archimedes principle. Say an object is partially immersed in water. The weight of water water displaced will be equal to weight of the entire object or just the part immersed in water?
Yes, when there is nothing above the surface and the object has the same mean density as water.Deebu R said:One more thing. Is there a case were the weight of water displaced equal the weight of the part of the body which is below water level?
Archimedes principle states that the buoyant force acting on an object immersed in a fluid is equal to the weight of the fluid that is displaced by the object.
The weight of an immersed object can be calculated by multiplying the density of the fluid, the volume of the displaced fluid, and the acceleration due to gravity.
Archimedes principle explains why objects float or sink when placed in a fluid. If the weight of the object is less than the weight of the displaced fluid, the object will float. If the weight of the object is greater, it will sink.
Archimedes principle is used in various applications such as designing ships and submarines, determining the density of an object, and calculating the weight of an object in water.
The density of an object affects its buoyancy because the more dense an object is, the more it will sink in a fluid. This is because the buoyant force acting on the object is equal to the weight of the displaced fluid, and a denser object will displace less fluid.
