   zero gravity

   noun

   • 1. the state or condition in which there is no apparent force of gravity acting on a body, either because the force is locally weak, or because both the body and its surroundings are freely and equally accelerating under the force.

   Weightlessness is the complete or near-complete absence of the sensation of weight, i.e., zero apparent weight. It is also termed zero g-force, or zero-g (named after the g-force) [1] or, incorrectly, zero gravity. Microgravity environment is more or less synonymous in its effects, with the recognition that g-forces are never exactly zero.

   Jun 19, 2020 · Zero gravity is not the absence of gravity, but a sensation of weightlessness caused by an acceleration that cancels out Earth's gravity. Learn how this works in airplanes, spacecraft and the International Space Station with examples and explanations by a Purdue University professor.

   Mar 7, 2017 · The answer, as given - is at no height is there zero gravity, because although, at vast distances, 1/r^2 means that the gravitatonal acceleration will be very low, it's not zero. Pluto is 5 billion kilometres from the Sun, but the reason it orbits the Sun is because, despite that huge distance, it still feels the gravitation acceleration of the ...

   weightlessness, condition experienced while in free-fall, in which the effect of gravity is canceled by the inertial (e.g., centrifugal) force resulting from orbital flight. The term zero gravity is often used to describe such a condition.

   May 15, 2023 · To help the astronauts adapt, NASA, as part of their training, subjects the astronauts to such an environment every day. The enclosed region of “zero” gravity is not located in space, but is created right here on Earth. The question is… how does NASA achieve this?

   Feb 15, 2012 · In microgravity, astronauts can float in their spacecraft – or outside, on a spacewalk. Heavy objects move around easily. For example, astronauts can move equipment weighing hundreds of pounds with their fingertips. Microgravity is sometimes called “zero gravity,” but this is misleading.
