Buoyant force is the upward force exerted by a fluid on an object immersed in it. This force is equal to the weight of the displaced fluid.
The buoyant force can be calculated using Archimedes' principle, which states that the buoyant force is equal to the weight of the fluid that is displaced by the object. This can be represented by the equation Fb = ρVg, where ρ is the density of the fluid, V is the volume of the displaced fluid, and g is the acceleration due to gravity.
The buoyant force is affected by the density of the fluid, the volume of the object immersed in the fluid, and the acceleration due to gravity. The shape and size of the object can also affect the buoyant force.
Yes, the buoyant force can be greater than the weight of the object. This is especially true for objects that are less dense than the fluid they are immersed in, such as a boat on water.
Buoyant force is what enables objects to float in a fluid. If the buoyant force is greater than the weight of the object, the object will float. If the buoyant force is less than the weight of the object, the object will sink.
