  2. Orders of magnitude (speed) - Wikipedia

    en.wikipedia.org/wiki/Orders_of_magnitude_(speed)

    To help compare different orders of magnitude, the following list describes various speed levels between approximately 2.2 × 10 −18 m/s and 3.0 × 10 8 m/s (the speed of light). Values in bold are exact.

  3. Tachyon - Wikipedia

    en.wikipedia.org/wiki/Tachyon

    The possibility of standard model particles moving at faster-than-light speeds can be modeled using Lorentz invariance violating terms, for example in the Standard-Model Extension. [ 19 ] [ 20 ] [ 21 ] In this framework, neutrinos experience Lorentz-violating oscillations and can travel faster than light at high energies.

  4. Speed of gravity - Wikipedia

    en.wikipedia.org/wiki/Speed_of_gravity

    Putting the Sun immobile at the origin, when the Earth is moving in an orbit of radius R with velocity v presuming that the gravitational influence moves with velocity c, moves the Sun's true position ahead of its optical position, by an amount equal to vR/c, which is the travel time of gravity from the sun to the Earth times the relative ...

  5. Faster-than-light - Wikipedia

    en.wikipedia.org/wiki/Faster-than-light

    In the context of this article, "faster-than-light" means the transmission of information or matter faster than c, a constant equal to the speed of light in vacuum, which is 299,792,458 m/s (by definition of the metre) [3] or about 186,282.397 miles per second. This is not quite the same as traveling faster than light, since:

  6. Velocity - Wikipedia

    en.wikipedia.org/wiki/Velocity

    While the terms speed and velocity are often colloquially used interchangeably to connote how fast an object is moving, in scientific terms they are different. Speed, the scalar magnitude of a velocity vector, denotes only how fast an object is moving, while velocity indicates both an object's speed and direction. [3] [4] [5]

  7. Beaufort scale - Wikipedia

    en.wikipedia.org/wiki/Beaufort_scale

    v = 0.836 B 3/2 m/s; v = 1.625 B 3/2 knots (=) where v is the equivalent wind speed at 10 metres above the sea surface and B is Beaufort scale number. For example, B = 9.5 is related to 24.5 m/s which is equal to the lower limit of "10 Beaufort". Using this formula the highest winds in hurricanes would be 23 in the scale.

    Some 95% of species disappeared on land and at sea as a result of global warming — with temperatures rising perhaps 10 degrees Celsius to 15 degrees Celsius (18 F to 27 F), Benton noted in his book.

    Uncrewed torpedo speed claims range from 60 knots (110 km/h; 69 mph) for the British Spearfish torpedo [64] to 200 knots (370 km/h; 230 mph) for the Russian VA-111 Shkval. [ 65 ] ^ a b Ground effect vehicles (a.k.a. "Wing-In-Ground effect vehicles") are classified as maritime vessels, rather than aircraft, by the International Maritime ...
