Question

1. compared with his mass and weight on the earth, an astronaut on mars, where the acceleration due to gravity is 1.7 m/s², has (a) less mass and less weight (b) less mass and the same weight (c) less mass and more weight (d) the same mass and less weight

Explanation:

Mass is an inherent property of an object and does not change with location. Weight is the force due to gravity, calculated as $W = mg$, where $m$ is mass and $g$ is the acceleration due to gravity. Since the acceleration due to gravity on Mars ($1.7\ m/s^{2}$) is less than on Earth ($9.8\ m/s^{2}$), with the same mass, the weight on Mars is less.

Answer:

D. the same mass and less weight
