Question

why astronauts are weightlessness in satellites.drive a relation for the weighlessness in space​

Answer 1

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.

Answer 2

Hey mate
Here is your answer :--

Astronauts in the space feel weightlessness because :-

1) They are in the state of free fall. Though they are not falling on the Earth, the only force acting on it is gravity

2) As no force other than gravitational force is acting, it is in free fall state and due to vacuum they feel weightless


Hope this help you mate
