ARTIFICIAL GRAVITY: the Describe how can artificial gravity be produced in a space craft

space craft To an astronaut, weightlessness in a satellite (or space craft) is highly inconvenient. To overcome this problem, artificial gravity can be created by spinning the space-craft around its own axis. If the frequency of rotation is prope, centripetal acceleration equals the acceleration due to gravity[9/12, 11:50 PM] mama jan: ahen So the estraining force is zero

Conclusion: The apparent weight of the body is zero, although the fonce of graity s ser appon the body. 1his is called "weigthlessness

WEIGHTLESSNESS IN SATELLITE:  Discuss weightiessness in a satellite. Ans: Weight a body in s frame of reference is equal but opposite to the force tha prevents it from falling in that relerence frame, The absence of this restraining force gives the impression of weight lessness, A satellite is an 'artificial moon is the spacecraft that moves round the carth in an orbit.
