The preceding first, third, and fourth answers are correct. Additionally, you should multiply the units, and remember that (1 kg) × (1 m/s²) ≡ 1 N. Then…
On the moon, 80 kg × 1.62 m/s² = 129.6 N and
on the earth, 80 kg × 9.80 m/s² = 784 N.
And check your spelling of "weigh."

Weight is determined by mass under the influence of gravity. Since the moon's gravitational field is one sixth of the Earth's Gravitational field, a persons weight is one sixth on the moon. The fact that the moon faces the Earth the same way has nothing to do with the force of the moon's gravitational field.

Weight is simply a person's mass times the local gravitational acceleration:
W = m * g
On the moon, an 80 kg person is
W = 80 * 1.62 = 129.6 N
On Earth the same person is:
W = 80 * 9.8 = 784 N

Weight is the same as force. F = ma
The acceleration of free fall is g. So a = g.
So use the formula F = mg.
On the moon F = 80 x 1.62 = 129.6N
On the earth F = 80 x 9.8 = 784N

will you kids stop sleeping in class your book will give you the conversion tables and formula then you can use your calculator to do the rest figure the moon is approx 1/6 g and 1kg = 2.25 lbs approx that should be close enough to get you past this question that anyone should be able to reason out provided their IQ is over 80 this is from memory so confirm these figures in your text book why do the worst math students always seem to take physics thinking it is easy

Mass x Gravity = weight
We know that the guy weighs 80kg and the gravity on the moon is 0.17. If you multiply 80kg x 0.17, you get 13.6.
On the earth, he'll weigh 80kg again.

this is like very basic physics! gravitational force is g*mass. since you already have the mass and you told us the g, just multiply them together! use a calculator! if you don't have one, there's one on the computer you're using! (start, programs, accessories)

on moon: 90kg*1.62=129.3N
on earth: 80kg*9.8=784N

784.8 kN on Earth
129.6 kN on the Moon (given your constant)
F=ma
