Nasa: The Way Things Fall
This site from NASA compares free falling motion to falling with air resistance. Discusses Galileo's experiment. Explains why we believe all objects free fall with the same acceleration.

Annenberg Learner: Amusement Park Physics: The Principles of Free Fall
An article describing free fall principles in roller coaster rides. In addition to the explanation of free fall, an experiment is described that allows you to test free fall with a cup of water. Part of a larger presentation on roller...

The Physics Classroom: Introduction to Free Fall
A lesson on free fall covers the fact that free-falling objects do not encounter air resistance and all free-falling objects (on Earth) accelerate downwards at a rate of approximately 10 m/s/s (to be exact, 9.8 m/s/s).
University of Maryland
University of Marylad: Computer Tutorials in Physics: Air Resistance
This site has a discussion of a college physics project in which the motion of an object under the influence of air resistance was modeled and studied. Procedure and modeling software are described and the results and the findings are...
