# At what height do you become weightless?

## At what height do you become weightless?

So you might ask, “What height above the Earth must astronauts reach to achieve weightlessness?” But it’s not any particular height or altitude that makes them weightless. Gravity is almost as strong at the height of the International Space Station as on the surface of the Earth — only about 10 percent weaker.

What does Zero G feel like?

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.

Can zero gravity be created on Earth?

Yes, it is possible to produce zero gravity condition on earth.

### At what height do you float in space?

In the 1900s, Hungarian physicist Theodore von Kármán determined the boundary to be around 50 miles up, or roughly 80 kilometers above sea level. Today, though, the Kármán line is set at what NOAA calls “an imaginary boundary” that’s 62 miles up, or roughly a hundred kilometers above sea level.

Do astronauts feel acceleration in space?

Astronauts in orbit travel at 28000 km/h but feel absolutely nothing, even if they’re outside. Similarly, inside a car you do not feel the speed, only the change in speed (i.e. acceleration – and note that acceleration can be in any direction: forward, backward, left, right, up or down).

Why does free fall not happen on the Earth?

At the time of free fall on the earth, in addition to gravitational force, the object experiences force of friction due to air. Thus, the free fall cannot happen on the earth. The velocity of the object increases due to acceleration due to the gravity of the earth.

## Would a human body decompose in space?

Halting decomposition And bacteria from the gut would still devour the soft tissues. But these bacteria need oxygen to function properly and so limited supplies of air would significantly slow down the process.

Is there no gravity in free fall?

Yes. Free fall is defined as “any motion of a body where gravity is the only force acting upon it.” In the vacuum of space, where there are no air molecules or supportive surfaces, astronauts are only acted upon by gravity.
