Question

why do you feel weightless in the International Space station?

Answer 1

1) In space we feel weightlessness because the earth's gravity has less effect on us.

The reason why you don't see gravitational effects between objects in a spacecraft is because gravity is a very, very weak force. Of the four basic forces that scientists are sure about, gravity is, by far, the weakest one.

The gravitational attraction between two small objects in a spacecraft would be overwhelmed by other forces, such as the force of the air being circulated throughout the spacecraft. Although the force of attraction is there, it is so weak that special care would have to be taken to notice it

2) astronauts and objects inside the ISS or other spacecraft appear to be floating because of speed!

The astronauts, the ISS itself and other objects in Earth orbit aren’t floating, they are actually falling. But they don’t fall to the Earth because of their huge orbital velocity. Instead, they fall around the Earth.
