Buoyant Force:The upward force exerted by a fluid on an object immersed in it, which opposes the weight of the object.
Pascal's Principle: The principle that states that when there is an increase in pressure at any point in a confined fluid, there is an equal increase at every other point in the fluid.
Bernoulli's Principle: The principle that states that as the speed of a fluid increases, its pressure decreases, and vice versa.
