Weightlessness - Wikipedia
Microgravity environment is more or less synonymous in its effects, with the recognition that g-forces are never exactly zero. Weight is a measurement of the force on an object at rest in a relatively strong gravitational field (such as on the surface of the Earth).

Microgravity - Simple English Wikipedia, the free encyclopedia
microgravity, zero gravity or weightlessness is the apparent absence of gravity such as that in freefall, outer space, or rapid deceleration. The lack of gravity is only an illusion.
Microgravity | Space Exploration, Astronauts & Zero-Gravity
2024年11月12日 · microgravity, a measure of the degree to which an object in space is subjected to acceleration. In general parlance the term is used synonymously with zero gravity and weightlessness, but the prefix micro indicates accelerations equivalent to one-millionth (10 −6) of the force of gravity at Earth’s surface.
Scientists Say: Microgravity - Science News Explores
2020年7月27日 · Microgravity is the experience of gravity that is only a fraction of the force we experience on Earth. Gravity is a force that attracts anything with mass to anything else that also has mass. The more mass, the greater the gravity.
What Is Microgravity, And How Does it Relate to Free Fall?
Microgravity is a unique condition that allows astronauts and objects in space to float as if they have no weight. It happens in space and is important for science and space exploration. In microgravity, researchers can do experiments that can’t be done on Earth, like studying how liquids move or how living things adapt to weightlessness.
What Is Microgravity? - NASA
2023年4月11日 · This article defines microgravity and explains how NASA simulates microgravity on Earth.
What is Microgravity? - NASA
2009年2月13日 · The condition of microgravity comes about whenever an object is in free fall. That is, it falls faster and faster, accelerating with exactly the acceleration due to gravity (1g). As soon as you drop something (like an apple) it is in a state of free fall.

Microgravity - NASA
2010年6月30日 · microgravity is used to denote the situation where gravity levels (inertial acceleration) are much less than the 1 x g (9.81 m/sec 2 or 32.17 ft/sec 2 ) experienced at the surface of the earth.
