Atmosphere of Earth
The atmosphere of Earth is the layer of gases, commonly known as air, that surrounds the planet Earth and is retained by Earth's gravity.

Barometric formula
The barometric formula, sometimes called the exponential atmosphere or isothermal atmosphere, is a formula used to model how the pressure (or density) of the air changes with altitude.

Density
The density, or more precisely, the volumetric mass density, of a substance is its mass per unit volume.

Drag (physics)
In fluid dynamics, drag (sometimes called air resistance, a type of friction, or fluid resistance, another type of friction or fluid friction) is a force acting opposite to the relative motion of any object moving with respect to a surrounding fluid.

Drag coefficient
In fluid dynamics, the drag coefficient (commonly denoted as: \scriptstyle C_\mathrm d\,, \scriptstyle C_\mathrm x\, or \scriptstyle C_\mathrm w\) is a dimensionless quantity that is used to quantify the drag or resistance of an object in a fluid environment, such as air or water.

Lift (force)
A fluid flowing past the surface of a body exerts a force on it.

Speed
In everyday use and in kinematics, the speed of an object is the magnitude of its velocity (the rate of change of its position); it is thus a scalar quantity.

Vortex-induced vibration
In fluid dynamics, vortex-induced vibrations (VIV) are motions induced on bodies interacting with an external fluid flow, produced by – or the motion producing – periodical irregularities on this flow.

Zero-lift drag coefficient
In aerodynamics, the zero-lift drag coefficient C_ is a dimensionless parameter which relates an aircraft's zero-lift drag force to its size, speed, and flying altitude.
