gravitational acceleration on moon= gravitational acceleration on earth/6
=g/6
=9.8/6 m/s²
g'=g/6
mass=51 kg
weight on moon=mass*g'
=51*9.8/6
=83.3 kg
hope this helps
The mass of the man would remain the same…
His weight would change. Assuming the man’s weight on earth is 51 N.
Since weight is a force, according to Newton’s second law, F = ma ( m = mass, a = acceleration due to gravity)
First lets find the mass of the man, as it is required to find his weight on the moon.
F = ma [taking a of earth as 10 m/s^2]
51 = m . 10 [divide 10 on both sides]
m = 51/10 = 5.1 Kg
Acceleration due to gravity on the moon is 83% less than the acceleration due to gravity on earth (1.622 m/s^2).
F = ma
F = 5.1 . 1.622 = 9.732 N
So a person weighting 51 N on earth would approximately weight around 10 N on the moon.
