An astronaut awakes in her closed capsule, which actu- ally sits on the Moon. Can she tell whether her weight is the result of gravitation or of accelerated motion? Explain.

No,  she cannot tell due to the theory of the relatively.

Explanation:

As for this to happen the capsule has to be of constant acceleration in order to move without being noticed.If the capsule slows down the speed would be reduced and the gravitation effects would be seen and another way would be for the capsular to spin constantly and have an acceleration motion of the outwards direction. As the capsule would have to the fairly small size and thus create a strong feeling of the gravity.
