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 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.
