Q. What does Archimedes' Principle primarily describe?
Answer: Buoyancy
Notes: Archimedes' Principle states that any object submerged in a fluid experiences an upward buoyant force equal to the weight of the fluid it displaces. This principle is fundamental in understanding why objects float or sink. It applies to both liquids and gases, and is crucial in various fields, including engineering and fluid mechanics. Archimedes, a Greek mathematician, discovered this principle in the 3rd century BC.
