  2. Time dilation - Wikipedia

    en.wikipedia.org/wiki/Time_dilation

    The high and low frequencies detected were not the classically predicted values: / + / The high and low frequencies of the radiation from the moving sources were measured as: [23] + / / = (+ /) / + / = (/) as deduced by Einstein (1905) from the Lorentz transformation, when the source is running slow by the Lorentz factor.

  3. Gravitational time dilation - Wikipedia

    en.wikipedia.org/wiki/Gravitational_time_dilation

    For example, considered over the total time-span of Earth (4.6 billion years), a clock set in a geostationary position at an altitude of 9,000 meters above sea level, such as perhaps at the top of Mount Everest (prominence 8,848 m), would be about 39 hours ahead of a clock set at sea level.

    If you travelled a year at 95% the speed of light; you'd age one year, and people on Earth would age 3.2 years! But if you were going 50% the speed of light it would only be 1.15 years. The effect ...

  5. Airflow - Wikipedia

    en.wikipedia.org/wiki/Airflow

    Airflow, or air flow, is the movement of air. Air behaves in a fluid manner, meaning particles naturally flow from areas of higher pressure to those where the pressure is lower. Atmospheric air pressure is directly related to altitude , temperature , and composition.

  6. Swept wing - Wikipedia

    en.wikipedia.org/wiki/Swept_wing

    When a swept wing travels at high speed, the airflow has little time to react and simply flows over the wing almost straight from front to back. At lower speeds the air does have time to react, and is pushed spanwise by the angled leading edge, towards the wing tip. At the wing root, by the fuselage, this has little noticeable effect, but as ...

  7. High-speed flight - Wikipedia

    en.wikipedia.org/wiki/High-speed_flight

    In high-speed flight, the assumptions of incompressibility of the air used in low-speed aerodynamics no longer apply. In subsonic aerodynamics, the theory of lift is based upon the forces generated on a body and a moving gas (air) in which it is immersed. At airspeeds below about 260 kn (480 km/h; 130 m/s; 300 mph), air can be considered ...

  8. Wind gradient - Wikipedia

    en.wikipedia.org/wiki/Wind_gradient

    Flow near the surface encounters obstacles that reduce the wind speed, and introduce random vertical and horizontal velocity components at right angles to the main direction of flow. [9] This turbulence causes vertical mixing between the air moving horizontally at various levels, which has an effect on the dispersion of pollutants , [ 1 ] dust ...

  9. Wind - Wikipedia

    en.wikipedia.org/wiki/Wind

    The thermal wind is the difference in the geostrophic wind between two levels in the atmosphere. It exists only in an atmosphere with horizontal temperature gradients. [5] The ageostrophic wind component is the difference between actual and geostrophic wind, which is responsible for air "filling up" cyclones over time. [6]
