  2. Escape velocity - Wikipedia

    en.wikipedia.org/wiki/Escape_velocity

    An alternative expression for the escape velocity v e particularly useful at the surface on the body is: = where r is the distance between the center of the body and the point at which escape velocity is being calculated and g is the gravitational acceleration at that distance (i.e., the surface gravity). [11]

  3. Atmospheric escape - Wikipedia

    en.wikipedia.org/wiki/Atmospheric_escape

    One classical thermal escape mechanism is Jeans escape, [1] named after British astronomer Sir James Jeans, who first described this process of atmospheric loss. [2] In a quantity of gas, the average velocity of any one molecule is measured by the gas's temperature, but the velocities of individual molecules change as they collide with one another, gaining and losing kinetic energy.

  4. Velocity - Wikipedia

    en.wikipedia.org/wiki/Velocity

    Bahasa Indonesia; Interlingua; Interlingue; ... The escape velocity from Earth's surface is about 11 200 m/s, and is irrespective of the direction of the object. This ...

  5. Longevity escape velocity - Wikipedia

    en.wikipedia.org/wiki/Longevity_escape_velocity

    "The first 1000-year-old is probably only ~10 years younger than the first 150-year-old."–Aubrey de Grey, 2005 [1]. In the life extension movement, longevity escape velocity (LEV), actuarial escape velocity [2] or biological escape velocity [3] is a hypothetical situation in which one's remaining life expectancy (not life expectancy at birth) is extended longer than the time that is passing.

  6. Biogerontology - Wikipedia

    en.wikipedia.org/wiki/Biogerontology

    This concept has been referred to as longevity escape velocity. Biomedical gerontology , also known as experimental gerontology and life extension, is a sub-discipline of biogerontology endeavoring to slow, prevent, and even reverse aging in both humans and animals.

    Bahasa Indonesia; Íslenska; Italiano ... Pioneer 10 became the first of five artificial objects to achieve the escape velocity needed to ... Wikipedia® is a ...

  8. Geocentric orbit - Wikipedia

    en.wikipedia.org/wiki/Geocentric_orbit

    The object's velocity equals the escape velocity, therefore it will escape the gravitational pull of the Earth and continue to travel with a velocity (relative to Earth) decelerating to 0. A spacecraft launched from Earth with this velocity would travel some distance away from it, but follow it around the Sun in the same heliocentric orbit. It ...

  9. Orbit insertion - Wikipedia

    en.wikipedia.org/wiki/Orbit_insertion

    An orbit insertion maneuver involves either deceleration from a speed in excess of the respective body's escape velocity, or acceleration to it from a lower speed. When the result is a transfer orbit , e.g. a descent orbit insertion, the maneuver is an orbit injection .
