Conservation of Momentum
One of the fundamental conservation laws of physics. In fluid mechanics it is expressed as the momentum equation, which describes the relationship between the acceleration of a fluid element and pressure gradient forces, viscous forces, and external forces.

In fluids, conservation of momentum manifests as the acceleration of a fluid parcel being determined by pressure gradient forces, viscous forces, and external forces, that is, applying Newton's second law point by point to a continuum yields the momentum equation.
