The acceleration of gravity on the surface of Mars is 3.7 m/s².Compared with his or her mass and weight on Earth, an astronaut on Mars has A)less mass and less weight. B)less mass and more weight. C)the same mass and less weight. D)less mass and the same weight.

Question

Quizplus · Accepted Answer

The mass of an object does not change with location, so the astronaut would have the same mass on Mars as on Earth. However, weight is a function of both mass and gravity, so the astronaut would have less weight on Mars due to the lower acceleration of gravity. Therefore, the correct choice is C: the same mass and less weight.
