Archimedes' Principle

An immersed body is buoyed up by a force equal to the weight of the fluid it displaces (for both liquids and gasses)

Atmospheric Pressure

The pressure exerted against bodies immersed in the atmosphere resulting from the weight of the air pressing down from above. At sea level, atmospheric pressure is about 101 kPa (kilopascals)

Barometer

Any device that measures atmospheric pressure

Bernoulli's Principle

The pressure in a fluid moving steadily without friction or external energy input decreases when the fluid velocity increases

Boyle's Law

The product of pressure and volume is a constant for a given mass of confined gas regardless of changes in either pressure or volume individually, so long as the temperature remains unchanged.

P1V1 = P2V2

Buoyant Force

The net upward force that a fluid exerts on an immersed object

Density

The amount of matter per unit volume

d=m/v d=g/mL d=g/cm^3

Pascal's Principle

A change in pressure at any point in an enclosed fluid at rest is transmitted undiminished to all points in the fluid

Pressure

The ratio of force to the area over which that force is distributed

P=force/area units Newtons/meters^2

Liquid P= weight densityXdepth

Principle of Flotation

When an object on a fluid floats because it has displaced a weight of fluid equal to its own weight
