An astronaut standing on the surface of the Moon throws a ball upwards. What will the ball do?
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → Go up and then come back to the surface of the Moon
The Moon has no air, but it does have gravity: its pull is about one-sixth of the Earth’s. The ball leaves the hand with an upward speed, so it rises; the Moon’s gravity slows it down until it stops for an instant, and then pulls it back to the surface. Because the pull is weaker, the ball rises higher and stays up longer than it would on the Earth.
