Free Fall Model 

written by Andrew Duffy

This simulation allows students to examine the motion of an object in free fall. Download below.  The user can control the initial height (0-20m), set an initial velocity from -20 to 20 m/s, and change the rate of gravitational acceleration from zero to 20 m/s/s (Earth's gravitational constant is ~9.8 m/s/s). Students can also launch the ball upward from any point on the line of motion. The free fall is displayed as a motion diagram, while graphs are simultaneously displayed showing position vs. time, velocity vs. time, and acceleration vs. time.

See Annotations Below for an editor-recommended tutorial that further explains how graphs are used to represent free fall motion.

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. To run the simulation, simply click the Java Archive file below.
