How does an airboat move when there isn't a motor in the water? The simulation teaches the forces related to the thrust and drag on an airboat. Scholars vary the boat mass and thrust force in order to view graphs of the changing force...

How does an airplane control its take off and descent? Scholars explore the forces acting on an airplane and control the angle of attack, wing profile, thrust, and airplane size. They learn about lift, drag, thrust, gravity, and the...

What is the steepness of a hill before a unicyclist slides down it rather than pedaling down it? The simulation graphs the wheel speed versus the unicycle speed as the rider goes down a hill. Scholars control the mass of the rider,...

Sometimes it appears that a bowling ball slides down the alley rather than rolling, while other times it appears to switch rolling directions at some point. Scholars control the bowling ball size, initial rotation, initial speed, and...

Do you weigh slightly less when an elevator first starts its descent? The simulation teaches the change in the force based on the acceleration, constant speed, or deceleration of an elevator. Scholars control the mass and acceleration...

How can people control a hot air balloon? The simple simulation allows scholars to adjust the payload mass, burner, and vent position on a hot air balloon and observe the changes in velocity and altitude over time. Challenge questions...
