Homework Statement


Hey, I'm new to the forum. I have taken introductory Physic, but missed the first month of class due to serious personal issues. Anyways here's my question:

Determine the weight of a 50kg object on the surface of the moon(Do not use g=1.63N/kg)

Mm(Moon)=7.4x10 to the power of 22kg


Homework Equations


Fg=Mg?




The Attempt at a Solution


Like I said, I am pretty lost, but I've come up with this so far:
Fg=Mg
Fg=(7.4x10 to the power of 22kg)(50kg)
I wouldn't be surprised if I was way off, but I've tried a few formulas and have been way off.

Thanks!

Homework Equations


Fg=Mg

While this is correct, you are using your M and g incorrectly.


The weight of an object on a planet, is nothing but the gravitational force of attraction between the mass and the planet.

So how do you find the force of attraction between two masses? (Hint: Newton's law of gravitation)
