buoyant force

a force that acts in the direction opposite to the force of gravity, making an object feel lighter

archimedes' principle

the buoyant force on an object is equal to the weight of the fluid displaced by the object


mass per unit of volume

pascal's principle

When force is applied to a confined fluid, the change in pressure, is transmitted equally to all parts of the fluid

hydraulic system

a system that multiplies force by transmitting pressure from a small surface area through a confined fluid to a larger surface area

bernoulli's principle

as the speed of a moving fluid increases, the pressure exerted within the fluid decreases
