  2. Terminal velocity - Wikipedia

    en.wikipedia.org/wiki/Terminal_velocity

    Terminal velocity is the maximum speed attainable by an object as it ... and the forces acting on the body balance each other more and more closely as the terminal ...

  3. Speed skydiving - Wikipedia

    en.wikipedia.org/wiki/Speed_skydiving

    The speed, achieved by the human body in free fall, is a function of several factors; including the body's mass, orientation, and skin area and texture. [1] In stable, belly-to-earth position, terminal velocity is about 200 km/h (120 mph). Stable freefall head down position has a terminal speed of 240–290 km/h (around 150–180 mph).

  4. Free fall - Wikipedia

    en.wikipedia.org/wiki/Free_fall

    With air resistance acting on an object that has been dropped, the object will eventually reach a terminal velocity, which is around 53 m/s (190 km/h or 118 mph [4]) for a human skydiver. The terminal velocity depends on many factors including mass, drag coefficient, and relative surface area and will only be achieved if the fall is from ...

  5. Equations for a falling body - Wikipedia

    en.wikipedia.org/wiki/Equations_for_a_falling_body

    This velocity is the asymptotic limiting value of the acceleration process, because the effective forces on the body balance each other more and more closely as the terminal velocity is approached. In this example, a speed of 50 % of terminal velocity is reached after only about 3 seconds, while it takes 8 seconds to reach 90 %, 15 seconds to ...

  6. Parachuting - Wikipedia

    en.wikipedia.org/wiki/Parachuting

    For human skydiving, there is often a phase of free fall (the skydiving segment), where the parachute has not yet been deployed and the body gradually accelerates to terminal velocity. In cargo parachuting, the parachute descent may begin immediately, such as a parachute-airdrop in the lower atmosphere of Earth, or it may be significantly delayed.

  7. Wingsuit flying - Wikipedia

    en.wikipedia.org/wiki/Wingsuit_flying

    A typical skydiver's terminal velocity in belly to earth orientation ranges from 180 to 225 km/h (110 to 140 mph). A wingsuit can reduce these speeds dramatically. A vertical instantaneous velocity of 40 km/h (25 mph) has been recorded.

  9. Vertical wind tunnel - Wikipedia

    en.wikipedia.org/wiki/Vertical_wind_tunnel

    A recreational wind tunnel enables human beings to experience the sensation of flight without planes or parachutes, through the force of wind being generated vertically. Air moves upwards at approximately 195 km/h (120 mph or 55 m/s), the terminal velocity of a falling human body belly-downwards. A vertical wind tunnel is frequently called ...
