## Do astronauts have the same mass in space?

In space, astronauts and their spaceship still have mass and are still acted upon by Earth’s gravity. In this sense, they still have weight, even though Earth’s gravitational force is smaller in orbit than it is on Earth’s surface (Box 1). However, they do not feel their weight because nothing is pushing back on them. …

## Your question: Why do astronauts bounce and appear to float on the moon as they walk?

Explanation: The moon’s gravity is about 1/4 as strong as the earth’s gravity. … The astronauts are used to walking on earth so when they push forward with their legs they tend to use the same amount of energy which is 4 times more than needed. That push causes them to rise, Newton’s second law. …

## Do astronauts lose weight in space?

Astronauts quickly lose weight in space and return to Earth a little slimmer than when they left, scientists said Thursday in releasing findings from NASA’s most elaborate medical research mission. … The weight loss is one of a number of rapid body changes observed during the flight. How much weight do astronauts lose in space? …

## Do astronauts weigh the same in space?

The first obstacle is that in the microgravity of space, their weight is essentially zero, all the time. But astronauts still have mass, which they can measure to determine what their weight on Earth would be, and to let medical researchers track changes in body mass due to deconditioning in orbit. Do astronauts have the …

## Question: Can astronauts measure weight in the international space station?

Astronaut Karen Nyberg using the Space Linear Acceleration Mass Measurement Device (SLAMMD) on board the space station. … But astronauts still have mass, which they can measure to determine what their weight on Earth would be, and to let medical researchers track changes in body mass due to deconditioning in orbit. How do you calculate …

## Why is it incorrect to say astronauts are weightless in space?

(A) An astronaut standing on Earth does not feel weightless because the ground creates a normal force that opposes the force of gravity. … However, since the astronaut is also moving forward super fast, he/she continuously falls around the Earth rather than crashing into the Earth. Is it true that an astronaut is weightless in …

## Are astronauts really weightless?

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. Are astronauts weightless when returning …

## Do astronauts gain weight in space?

Astronauts quickly lose weight in space and return to Earth a little slimmer than when they left, scientists said Thursday in releasing findings from NASA’s most elaborate medical research mission. Can you get fat in space? He explains that, due to being in a weightless environment, astronauts’ muscles do not need to work as hard …

## Do astronauts weigh less in space?

In space, astronauts and their spaceship still have mass and are still acted upon by Earth’s gravity. In this sense, they still have weight, even though Earth’s gravitational force is smaller in orbit than it is on Earth’s surface (Box 1). However, they do not feel their weight because nothing is pushing back on them. …

## You asked: Why does an astronaut’s weight change in space but not his mass?

The weight of an object is a force. It is the force with which a body is attracted toward Earth or another celestial body. This means that when you are in space, away from Earth, objects do not weight anything since they do not feel gravitational attraction to the Earth. What objects have though in …
