This is my favorite animation for showing the independence between horizontal and vertical projectile motion. It starts with a helicopter traveling at a constant, horizontal, velocity. A picture is taken every second of flight to show the spacing. Next the helicopter drops a passenger straight down. Again a picture is taken every second to show the position. Then the helicopter is traveling horizontally when it drops a passenger. Again pictures are take and the connection between horizontal and vertical motion is shown. Finally, an animations shows two helicopters traveling at different velocities. They both drop their passengers at the same time from the same altitude. Both passengers hit the ground at the same time but at different horizontal positions.
