## What is the weight in Outer Space traveling with constant velocity?

zero
And there would be no weight in outer space because there’s no body to exert gravity, and it says they’re traveling with constant velocity. So, there won’t be any perceived weight due to the ship pushing on them either. So, d) is zero.

### Does weight change with constant velocity?

If they’re going at a constant velocity then there is NO extra force. Answer 2: From classical physics, Force = mass x acceleration. So, for a person at rest, their weight is simply their mass times the acceleration due to gravity.

#### Is there constant velocity in space?

If u thrown an object into the space, it will continue moving in its straight path with the same velocity of ur initial throw. And it maintains constant velocity until some external forces (either moving or stable solid, liquid, gas particles/objects) changes its direction or speed.

Does weight remain constant in space?

While the weight of an object varies in proportion to the strength of the gravitational field, its mass is constant, as long as no energy or matter is added to the object. For example, although a satellite in orbit (essentially a free-fall) is “weightless”, it still retains its mass and inertia.

What is the weight of a 70 kg astronaut on Earth?

160 lbs
On Earth, a 70 kg person weighs 706 Newtons (or 160 lbs). In orbit, the astronauts weight is 632 Newtons (142 lbs).

## What is the weight of a 68 kg astronaut on Earth?

the actual weight of a astronaut( m) = 68-kg. 9.8×68 = 666.4 = 6.7×10^2newton. 1.7× 68 = 115.6 =1.6×10^2 newton. there is no weight and the answer is 0 newton.

### Does apparent weight depend on velocity?

That is because the speed needs to be changing to affect the apparent weight! If the elevator is moving at a constant speed there is no difference in the apparent weight compared to when it is sitting still.

#### Does weight increase with acceleration?

The weight of an object temporarily increases with its acceleration because of inertia and temporarily increasing the density of the particles (the particles of the object become more densely packed in forward motion against resistant forces) of the object.

Is your weight 0 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.

Is there g-force in outer space?

The short answer is “yes”—there is gravity in space. Look back at the gravitational equation above. What changes in that equation as you move from the surface of the Earth into space? The only difference is the distance between you and the center of the Earth (the r).

## Why astronauts are weightless in space?

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.

### Does weight change in space?

While Astronauts may not weigh anything in space and can float around freely, their body shape and size does not change. They still take up just as much space as they do here on Earth. This is the important difference between mass and weight.
