Final answer:

In water, the force experienced by a submerged object is known as buoyancy, described by Archimedes' Principle as the net upward force equal to the weight of the displaced fluid.

Step-by-step explanation:

The force experienced by an object submerged in water corresponds to buoyancy. Buoyant force is a net upward force on any object in any fluid, including water. According to Archimedes' Principle, this buoyant force is equivalent to the weight of the fluid that the submerged object displaces. This principle explains why objects may float, sink, or remain suspended in water. If the buoyant force is greater than the object’s weight, it rises and floats. If it's less, the object sinks. If the buoyant force and the object's weight are equal, the object will stay at that depth without rising or sinking.
