How Hot Air Balloons Work
A brief description of how Hot Air Balloons work. This site is part of Marshall Brain's HowStuffWorks.com. This site includes fascinating pictures of balloons at different stages of their flight.
Projectile Motion
A very good little applet illustrating projectile motion with and without air resistance.
Hot Science: Floating and Sinking
A nice little demonstration of the concept behind hot air balloons and densities.
Falling Parachutes and Air Resistance 1
A simulation of a mass falling under the influence of gravity while attached to a parachute.
Falling Parachutes and Air Resistance 1
A simulation of two masses (may be altered) falling under the influence of gravity while attached to different sized parachutes.
Thermals
A collection of practicals on air pressure changes due to heat.
Newton's Second Law Experiment
Download a Java Applet simulating an air track experiment (with variable friction) in which a glider is accelerated by a weight hanging over a pulley - demonstrating Newton's 1nd Law
How Air Conditioners Work
A brief description of how Air Conditioners work. This site is part of Marshall Brain's HowStuffWorks.com.
Air Track
Impressive interactive Shockwave/ Flash animation simulating collisions on an air track. Subscription required but with 30 day free trial.
Explorescience: Golf Range
This activity lets you study the projectile range equation in a "golf" like setting. Vary the velocity and angle of the ball to get a hole in one. Add air resistance for more of a challenge. Could ...
