    3.3–5.0 × 10 −9 Average walking speed—below a speed of about 2 m/s, it is more efficient to walk than to run, but above that speed, it is more efficient to run. 2.39

  4. Speed of gravity - Wikipedia

    en.wikipedia.org/wiki/Speed_of_gravity

    Photons were detected 1.7 seconds after peak gravitational wave emission; assuming a delay of zero to 10 seconds, the difference between the speeds of gravitational and electromagnetic waves, v GW − v EM, is constrained to between −3 × 10 −15 and +7 × 10 −16 times the speed of light. [30]

  5. Amdahl's law - Wikipedia

    en.wikipedia.org/wiki/Amdahl's_law

    Then we are told that the 1st part is not sped up, so s1 = 1, while the 2nd part is sped up 5 times, so s2 = 5, the 3rd part is sped up 20 times, so s3 = 20, and the 4th part is sped up 1.6 times, so s4 = 1.6. By using Amdahl's law, the overall speedup is

  6. Speed - Wikipedia

    en.wikipedia.org/wiki/Speed

    Average speed does not describe the speed variations that may have taken place during shorter time intervals (as it is the entire distance covered divided by the total time of travel), and so average speed is often quite different from a value of instantaneous speed. [3] If the average speed and the time of travel are known, the distance ...

  7. List of vehicle speed records - Wikipedia

    en.wikipedia.org/wiki/List_of_vehicle_speed_records

    The following is a list of speed records for various types of vehicles.This list only presents the single greatest speed achieved in each broad record category; for more information on records under variations of test conditions, see the specific article for each record category.

  8. Equations for a falling body - Wikipedia

    en.wikipedia.org/wiki/Equations_for_a_falling_body

    In all cases, the body is assumed to start from rest, and air resistance is neglected. Generally, in Earth's atmosphere, all results below will therefore be quite inaccurate after only 5 seconds of fall (at which time an object's velocity will be a little less than the vacuum value of 49 m/s (9.8 m/s 2 × 5 s

  9. Tangential speed - Wikipedia

    en.wikipedia.org/wiki/Tangential_speed

    One moves faster if the rate of rotation increases (a larger value for ω), and one also moves faster if movement farther from the axis occurs (a larger value for r). Move twice as far from the rotational axis at the centre and you move twice as fast. Move out three times as far, and you have three times as much tangential speed.
