Question

The acceleration due to gravity is lower on the Moon than on Earth. What can be said about the mass and weight of an astronaut on the Moon's surface, compared to Earth?

Answer 1

See below

Explanation:

As mass being independent of 'g' is same on earth and moon.

Talking about weight,
By observing a very basic equation of weight :-
`W = mg`,
we can clearly see that weight is nothing but,
mass of object `* g`

So, this implies that weight of an astronaut is different on earth than that on moon.

Rather, it is found that the value of `'g'` is `(1/6)^(th)` times on moon than that on earth.
`i.e.,` `g_"e" = 1/6 * g_"m"`

So, mass of the astronaut is same but weight is weight becomes `(1/6)^(th)` on moon
