A ball is thrown forward at 5 m/s.

Gravity pulls the ball downward on both Earth and the moon, so its path curves down in both places. Earth’s gravitational acceleration is stronger, about 9.8 m/s² compared with about 1.6 m/s² on the moon, so the ball curves down more sharply on Earth. The correct choice is “The ball would curve down more sharply on Earth than on the moon.”
