Two Dimensional Air Drop Model
written by Francisco Esquembre
supported by 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.

Please note that this resource requires at least version 1.5 of Java (JRE).

### AAAS Benchmark Alignments (2008 Version)

#### 4. The Physical Setting

4B. The Earth
• 6-8: 4B/M3. Everything on or anywhere near the earth is pulled toward the earth's center by gravitational force.
4F. Motion
• 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

11B. Models
• 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.

### AAAS Benchmark Alignments (1993 Version)

#### 11. COMMON THEMES

B. Models
• 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.
