Two Dimensional Air Drop Model
the National Science Foundation
The Two-Dimensional Air Drop model shows a Red Cross airplane planning to drop supplies to a small island. As captain of the plane, the user must drop the package at the right moment so that it doesn't fall on the ocean.
The Two-Dimensional Air Drop model was created using the Easy Java Simulations (Ejs) modeling tool. It is distributed as a ready-to-run (compiled) Java archive. Double clicking the ejs_murcia_mech_TwoDimensionalAirDrop.jar file will run the program if Java is installed.

6-8: 4B/M3. Everything on or anywhere near the earth is pulled toward the earth's center by gravitational force.
9-12: 4F/H2. All motion is relative to whatever frame of reference is chosen, for there is no motionless frame from which to judge all motion.
9-12: 4F/H8. Any object maintains a constant speed and direction of motion unless an unbalanced outside force acts on it.
11. Common Themes
6-8: 11B/M1. Models are often used to think about processes that happen too slowly, too quickly, or on too small a scale to observe directly. They are also used for processes that are too vast, too complex, or too dangerous to study.

11. COMMON THEMES
11B (6-8) #3. Different models can be used to represent the same thing. What kind of a model to use and how complex it should be depends on its purpose. The usefulness of a model may be limited if it is too simple or if it is needlessly complicated. Choosing a useful model is one of the instances in which intuition and creativity come into play in science, mathematics, and engineering.
