A seagull scoops up a clam and takes it high above the ground. While flying parallel to the ground, the seagull lets go so that the clam lands on a rock below and cracks open. Then the seagull alights and enjoys lunch. A beachcomber on the beach sees the clam fall along a parabolic path, just as a projectile would. Why does the clam not drop straight down? What does the path of the falling clam look like to the bird?
