Free Fall Air Resistance Model
written by Andrew Duffy
This simulation allows students to compare the motion of free falling objects with and without the influence of air resistance. Air resistance is the result of collisions of the object's leading surface with air molecules. On Earth, objects falling through the air usually encounter some sort of air resistance, though the amount is dependent upon several factors. In this model, a blue ball falls under the influence of gravity alone. A falling red ball is subject to both gravity and air resistance. The user can adjust the amount of air resistance with a slider. When the simulation is played, graphs are simultaneously plotted that show position vs. time, velocity vs. time, and acceleration vs. time for both falling balls.
See Annotations Below for an editor-recommended, interactive tutorial that further explains free fall and air resistance.

The Physics Classroom: Free Fall and Air Resistance (Editor: Caroline Hall)
This editor-recommended interactive tutorial from The Physics Classroom will help students understand the factors that cause air resistance and how this impacts the motion of free fall. The tutorial engages students with animations, free-body diagrams of an elephant and a mouse in free-fall, and a glimpse of terminal velocity. Students will also do simple calculations.
This resource is part of a Physics Front Topical Unit.
Topic: Kinematics: The Physics of Motion
Unit Title: Motion in One Dimension
How does air resistance affect the motion of a free-falling object? In this model, a blue ball falls under the influence of gravity alone. The red ball is subject to both gravity and air resistance. Adjust the amount of air resistance with a slider, then watch the changes in the motion graphs.Link to Unit:
