Answer 2

If you were to fall off a boat, it's unlikely that your first thoughts would involve the ancient Greek philosopher Archimedes. However, Archimedes' principle helps to explain what is happening to your submerged body. As an object is submerged in water, it moves, or displaces, water according to how much it weighs. Archimedes found that the water will push upward against the object with a force equal to the weight of water that is displaced.
