Charlotte is curious about how her weight would change if she traveled from Earth to the moon. How is her weight different on Earth and on the moon?

• She weighs the same because the force of attraction is equal.

• She weighs more on Earth because the force of attraction is stronger.

• She weighs less on Earth because the force of attraction is weaker.

• She weighs more on Earth because the force of attraction is weaker.
