Mass isn’t dependent on gravity, so the man would still be 66
66
k
g
. His weight, however, is calculated using the formula:

=
w
=
m
g

So, weight, equal mass times the acceleration due to gravity. On the moon, acceleration due to gravity is 1.62/²
1.62
m
/
s
²
. If we plug these “givens” in, we get:

=(66)(1.62/²)
w
=
(
66
k
g
)
(
1.62
m
/
s
²
)

Therefore, weight equals 106.92
106.92
N

w

The mass of the person would be 66 kg on both Earth and the Moon.
