Density
The Mass Per Unit Volume Of A Substance, Affecting Buoyancy And Pressure.

Buoyancy
The Upward Force Exerted By A Fluid On An Object, Described By Archimedes Principle.

Archimedes Principle
A Principle Stating That The Buoyant Force On An Object Equals The Weight Of The Fluid Displaced.

Pascals Principle
A Principle Stating That Pressure Applied To A Confined Fluid Is Transmitted Equally In All Directions.

Bernoullis Principle
A Principle Stating That As The Speed Of A Fluid Increases, Its Pressure Decreases.

Fluid Dynamics
The Study Of Fluids In Motion, Including Concepts Such As Bernoulli Principle.

Mechanical Energy
The Sum Of Kinetic And Potential Energy In A System.

Thermodynamics
The Study Of Heat, Energy, And Work, Governed By The Laws Of Thermodynamics.

Law Of Conservation Of Energy
A Fundamental Law Stating That Energy Cannot Be Created Or Destroyed, Only Transformed.

First Law Of Thermodynamics
A Law Stating That Energy Is Conserved In Thermodynamic Processes, Equivalent To The Law Of Conservation Of Energy.
