Question

acceleration due to gravity on mars is 3.7m/s2.compared with her mass and weight on the earth an astronaut on mars has: (a) less mass and less weight
(b)more mass and more weight (c) the same mass and less weight
d) the same mass and more weight

Answer 1

Answer:

c) same mass and less weight

Explanation:

Mass is a physical quantity which is independent of where you stand.

Mass is basically the quantity which you get when you stand on a weighing machine for example 50 kg

Weight is Mass X acceleration due to gravity (which is dependent on acceleration of gravity of the planet)

We know that acceleration due to gravity on earth is 9.8 m/s² which is more than that of mars's and weight is directly proportional to acceleration due to gravity

Hence the answer is C
