Which principle explains the upward force felt when submerged in water?

The correct choice is based on Archimedes’ Principle, which states that any object submerged in a fluid experiences an upward buoyant force equal to the weight of the fluid displaced by the object. This principle is fundamental in understanding why objects feel lighter when submerged.

When a diver enters the water, their body displaces a volume of water, and the water exerts an upward force on them that counteracts their weight. This force is felt as the buoyancy that allows divers to float or ascend in the water. Without Archimedes’ Principle, we would not have a clear explanation of why objects behave the way they do in a fluid environment.

The other principles listed do not directly describe this buoyant force. Bernoulli's Principle relates to the behavior of fluids in motion and the relationship between velocity and pressure, while Boyle's Law deals with the relationship between the pressure and volume of gas in a closed system. Pascal's Principle explains how pressure is transmitted through a fluid but does not specifically address the upward force experienced by a submerged object. Thus, Archimedes’ Principle is the key to understanding buoyancy in water.
