Archimedes, Pascal, and Bernoulli
Archimedes Law states that the buoyant force on a submerged object is equal to the weight of the fluid that is displaced by the object.
Ex: A ship displaces the same amount of water that it weighs.

Pascal’s Law states that pressure applied to a fluid is transmitted unchanged throughout the fluid.
Ex: Hydraulic Jack
Formula: Pressure = Force / Area

Bernoulli’s Law states that as the velocity of a fluid increases, the pressure exerted by that fluid decreases.
Ex: Blowing on a piece of paper while holding it in the air makes the whole piece of paper go flap in the area because the pressure has decreased in the air because the velocity has increased.
