Question

How, why, when do we feel weightlessness?

Answer 1

Say, an astronaut of mass M is in a satellite which is moving with a constant speed along the orbit. When the satellite/astronaut are orbiting the earth,both of them are attracted towards the centre of earth and both fall towards with same acceleration ' g '. Thus astronaut is unable to exert weight on the floor of the satellite, in turn satellite does not provide normal reaction on the astronaut. Therefore astronaut feels weightlessness.

thank you mr. modern spock :)
May the mass times acceleration be with you !
