What planet would have the least gravity and which would have the most?

• Mercury

• Jupiter

• Mars

• Venus

Why can you jump higher on the Moon than on Earth?

• You can jump higher on the Moon because it has more gravity than Earth.

• Since the Moon has less mass than the Earth it will have less gravity. Therefore, it doesn't pull as much as the Earth. That is why you jump higher.

• Since the Moon has more mas than the Earth, the Moon will pull more and therefore you will jump higher than on Earth.

• You will jump higher on the Moon because it has less gravity than the Earth.
