F = mg

This is just a reinforcement that:

# WEIGHT is the FORCE on a mass due to a gravitational field.

# MASS is how much matter there is in a body

**REMEMBER THAT THESE TWO ARE DIFFERENT!**

Other than that, you can use the equation:

(1)\begin{equation} F = mg \end{equation}

To figure out the weight of masses on other planets or places with a different gravitational acceleration.

e.g.

- Say you're a lardass and you weigh like $200 kg$s.
- On Earth, you'd have a weight of:
- $W = mg$
- $W = 200 \times 9.8$
- $W = 1960 N$

- On the Moon, you'd have a weight of:
- $W = mg$
- $W = 200 \times 1.6$
- $W = 320 N$
