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 .

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.

The sensation of a complete or near-complete absence of weight is termed as weightlessness. It is commonly experienced by astronauts orbiting the space. Know what causes weightlessness and more.

The phenomenon of "weightlessness" occurs when there is no force of support on your body. When your body is effectively in "free fall", accelerating downward at the acceleration of gravity, then you are not being supported.

Absence of gravity is known as weightlessness. It is like floating, the feeling you get when a roller coaster suddenly goes down. Astronauts on the International Space Station are in free fall all the time.

2023年11月22日 · Your chest feels compressed and you may have some difficulty breathing. Yet, in about 8 and a half minutes, you are in outer space, experiencing an entirely different sensation: weightlessness.

Q: What exactly is weightlessness? A: Weightlessness is the state in which a person feel no weight. It is not when there is no gravity at all; it is given by the fact that one experience the state of having fallen freely, when the force of gravity is rebalanced by the object’s inertia. Q: Is Weightlessness the Same as Being in Orbit?
