Free Fall Air Resistance Model 

written by Andrew Duffy

The Free Fall Air Resistance model allows the user to examine the motion of an object in free fall, and motion under the effect of air resistance.  This is simply one-dimensional motion (vertical motion) under the influence of gravity.  The blue ball moves under the influence of gravity alone.  The red ball moves under the influence of gravity and air resistance - the strength of the air resistance parameter can be adjusted.

The Free Fall Air Resistance 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_airresistance.jar file will run the program if Java is installed.
