# At what height do you become weightless?

## At what height do you become weightless?

Any object that is falling freely is weightless, no matter where it happens to be. This can be the International Space Station at a height of 200 miles, a NASA reduced-gravity airplane at a height of several thousand feet, a drop tower at several hundred feet, or you jumping off a chair at 3 feet.

## Why don t Rockets go straight up?

Why do rockets curve when they fly into space instead of going straight up? A: If a rocket just flew straight up, then it would fall right back down to Earth when it ran out of fuel! Rockets have to tilt to the side as they travel into the sky in order to reach orbit, or a circular path of motion around the Earth.

## How fast is 7 g force in mph?

7 Standard Gravity to Miles Per Hour Per Second = 153.

## Is 1 g acceleration possible?

constant 1g acceleration is the only way to achieve relativistic effects and get a spacecraft across significant distances in a human lifetime as measured aboard the spacecraft. About right. At 1g, you get to relativistic speed in about 1 year. At 0.

## How many G's is a car's acceleration?

So, 0-60 mph in 10 seconds will expose you to 0.

## Do G forces exist in space?

In both cases there is a gravitational force on the human but this gravitational force causes the human to accelerate. ... And yes, this is why astronauts feel weightless in orbit even though there is indeed gravity in space.

9 g's

## How many G's are in space?

Typical examples
Exampleg-force*
Space Shuttle, maximum during launch and reentry3 g
High-g roller coasters3.

## Why is there gravity on Earth but not in space?

Anything with mass creates gravity. The gravity generated by the Sun, Earth, the Moon, and other planets stretches throughout outer space. ... On Earth, astronauts feel the force of gravity as weight, because Earth's surface prevents them from falling. In outer space, however, there is no ground to push against astronauts.

## Why can't humans breathe in space?

We cannot breathe in space because there is no air in space. Without air in your lungs, blood will stop sending oxygen to your brain and you'll pass out after about 15 seconds.

## Why is there no gravity in free fall?

Earth-orbiting astronauts are weightless for the same reasons that riders of a free-falling amusement park ride or a free-falling elevator are weightless. They are weightless because there is no external contact force pushing or pulling upon their body. In each case, gravity is the only force acting upon their body.
