Archimedes' principle states that the buoyant force on an object is equal to the density of the fluid it displaces.
true?
True. Archimedes' principle states that the buoyant force exerted on an object submerged in a fluid is equal to the weight of the fluid that the object displaces. This principle helps explain why objects float or sink in a fluid. To understand why this principle holds true, we can break it down into a few steps:
1. To calculate the buoyant force, we need to know the density of the fluid in which the object is submerged. The density of a fluid is the measure of how much mass is contained within a unit volume of the fluid.
2. The buoyant force is equal to the weight of the displaced fluid. When an object is placed in a fluid, it pushes the fluid aside, creating a space that the fluid used to occupy. This displaced fluid has weight, and the buoyant force is the gravitational force acting on this weight.
3. The weight of the displaced fluid is proportional to the volume of the object submerged and the density of the fluid. The more fluid that is displaced, and the denser the fluid, the greater the buoyant force.
Based on these principles, we can conclude that the buoyant force on an object is indeed equal to the density of the fluid it displaces.
