An astronaut spends 3 months in space and then returns to Earth. When she returns to Earth, her muscles have weakened. This is because of the stronger gravitational force that was exerted on her muscles in space.
True or false?

False!

ericwise · Answer

There is less gravity in space, therefore the astronaut doesn't need as much strength as on earth which has higher gravitational forces.

ericwise · Answer

The astronaut would be weaker due to the lack of gravity in space

anonymous · Answer

false, muscles are week because it is 0 gravity so everything is weightless. on earth you are using your muscles a little bit every second but up there muscles start to deteriorate because of non use

ericwise · Answer

not because of the "presence" of gravity in space-- which there is less or negligible amounts

anonymous · Answer

thats what i said

anonymous · Answer

yeah if there was a pull of gravity your muscles would stay the same because you are using them
