**Fluid mechanics** is the study of the motion of fluids and the forces that leads to these motions. It can be further classified into two categories: fluid statics (studies of fluids at rest) and fluid dynamics (studies of fluids in motion). The "fluid" in the term fluid mechanics is defined^{[1]} to be "a substance which deforms continuously under the action of a shear stress", which includes both liquids and gases.
