Bernoulli's Principle
When the speed of a fluid increases, the pressure exerted by the fluid decreases.
Archimedes' Principle
Buoyant force on an object is equal to the weight of the fluid displaced by the object.
Pascal's Principle
When a force is applied to a confined fluid, an increase in pressure is transmitted equally to all parts of the fluid
F / A
pressure
N
newtons
float
An object will _______ in a fluid that is denser than the object
buoyant force
