17. Answer Breifly VII

 

An astronaut float in a space shuttle because both are in the state of motionstate of reststate of weightlessness.

Astronauts are not floating but falling freely around the earth due to their less orbital velocityzero orbital velocityhuge orbital velocity. Since space stations and astronauts have lesser accelerationhigher accelerationequal acceleration, they are under free-fall conditions. Hence, both the astronauts and the space station are in a state of motionstate of weightlessnessstate of rest.
