There is no atmosphere on the Moon. The Moon exerts less gravitational force than Earth. Space suits helped them jump higher. The Moon rotates faster than Earth does.
I gave my students this multiple choice question: When people walked on the Moon, they found that they could jump higher than they could back on Earth. Why is this true?

Only one answer is correct among these 4 choices:
- There is no atmosphere on the Moon.
- The Moon exerts less gravitational force than Earth.
- Space suits helped them jump higher.
- The Moon rotates faster than Earth does.

Could you tell me which one is correct?

The Moon exerts less gravitational force than Earth.
