The Free Fall model allows the user to examine the motion of an object in freefall. This is simply one-dimensional motion (vertical motion) under the influence of gravity.
The Free Fall 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_bu_freefall.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.
4G. Forces of Nature
9-12: 4G/H1. Gravitational force is an attraction between masses. The strength of the force is proportional to the masses and weakens rapidly with increasing distance between them.
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.
6-8: 11B/M2. Mathematical models can be displayed on a computer and then modified to see what happens.
