24Weightlessness ocurs when a body falls freely towads earth....in satellite hte astronaut falls freely towards earth=> weightless...whereas on moon its not the case..so some weight
again gravitation......bt easier this time.....
well we know that when we re in a satellite we r weightless....moon is also a satellite of earth.....so why aren't we weightless in moon????
not my original question.....

3practically i think its impossible for us to say dat the astranouts in satellites experience weightlessness at all instant of time
In jee syllabus we have circular orbit.See the person in the satellite which is orbiting the earth in a circular path experience centrifugal acceleration of g (radially outward) and the acceleration due to gravity is (g radially inwards),So the net effect is zero acceleration dat is he feels weightless,
In fact by saying acceleration due to gravity is g which itself an approximation u know it very well.
19this is turning out to be a rath sir questionaire...uselessly !
check out the english terminology here..."on " the moon and "inside " the satellite
actually the weight that we feel is the normal force from the surface on which we are resting. in a satellite,wt of the body is fully nullified by centrifugal force but "on" the moon this weight is partially nullified so that N≠0 on the moon!
49we can think like the gravitational field inside a hollow spheree and on a hollow sphere
earth plays no role in weight on moon
and however heavy the satellite is u will be weightless inside it
