Can you time the speed of your car perfectly so you only hit green lights? The challenge in the simulation is to alter the timing of the lights or the speed of the car in order to do just that. Scholars learn about angular speed as they...

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...

Most water fountains are designed to keep the water inside the fountain, but how are they designed to shoot up and out without the water leaving the fountain? Scholars vary the launch angle, fountain height, launch speed, and...

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...

Students measure the speed of moving marbles and use the results to calculate velocity and momentum. They analyze the events preceding a Japanese train crash.
