This interactive simulation shows an airplane flying at constant horizontal velocity preparing to drop relief supplies to a small island. Download Simulation Below As captain of the plane, you must determine when to release the package and activate the release button. The trajectory of the falling package is traced onscreen. If you were too far off, the package will drop in the ocean. The motion can be viewed from the perspective of a person standing on the island or an airplane flying nearby. Extend the learning by activating air friction to see how this variable affects the motion of the projectile. Editor's Note: Students may insist that there is a horizontal force acting upon the package since it has a horizontal motion. See Annotation for an editor-recommended tutorial that will explain what is happening (the horizontal motion of the package results from its inertia). This item was created with Easy Java Simulations (EJS), a modeling tool that allows users without formal programming experience to generate computer models and simulations.
