The only stress is the normal stress, which is referred to as the pressure. σii = -p σn = -p, which is compressive, as it ...

The momentum of a piece of matter in movement is equal to the product of its mass by its velocity. In general, the velocity is a three-dimensional vector, ~u, and on a per-volume basis ...

Lift (force)
A fluid flowing past the surface of a body exerts a force on it. Lift is the component of this force that is perpendicular to the oncoming flow direction. It contrasts with the drag force, which is the component of the surface force parallel to the flow direction. If the fluid is air, the force is called an aerodynamic force. In water, it is called a hydrodynamic force.
