As others have mentioned (in paraphrase) if you were on the moon and shot a cannonball parallel to the ground, it would travel for awhile in that direction, while also falling toward the Moon due to gravitational acceleration. Eventually it hits the ground. Now, shoot the cannonball out faster. It goes quite a bit farther before still eventually falling and hitting the ground. Shoot it out even faster yet, and it goes so far that even as it falls, the surface of the round Moon is curving away from it noticeably. It is only being accelerated (pulled) toward the center of the Moon, but it has enough starting velocity so that it might travel all the way to the other side of the Moon before hitting the ground. Finally, with an even faster shot, it travels all the way around the Moon and hits the back of the cannon. Or, if you move the cannon, it keeps traveling around the Moon, in orbit, still with only its initial velocity, and the only pull coming from the Moon, toward its center. Spencer |
