Why is it impossible for an astronaut inside an orbiting space station to go from one end to the other by walking normally? A. In an orbiting station, the gravitational force is too large and the astronaut can't take his feet off the floor. B. It is impossible to walk inside an orbiting space station because its rotation is too fast. C. In an orbiting station, after one foot pushes off there isn't a friction force to move forward. The astronaut "jumps" on the same place. D. In an orbiting station, after one foot pushes off there isn't a force to bring the astronaut back to the "floor" for the next step.

Answer: Option D is Correct!

In an orbiting station, after one foot pushes off there isn't a force to bring the astronaut back to the "floor" for the next step

Explanation:

Imagine how hard it is to jump as high as 6 meters on earth. This is as a result of the earth's gravitational pull, also known as the force of gravity, which is the force by which the earth attracts objects to towards it's center. This force of gravity accounts for the weight of a body, according to the equation below:

w=mg

Where;

W = weight of body

m = mass of body

g = acceleration due to gravity

But in space, the gravitational pull rule doest not apply. Because the moon's gravity is 1/6 of of the Earth, this leads to weightlessness in space. As a result, whenever an astronaut tries to walk normally inside an orbiting space station, there isn't enough gravitational pull to allow that. He gets thrown up due to weightlessness in space.
