Free Fall Ride JS Model
written by
Michael R. Gallis
This mobile-friendly model allows students to design a free-fall ride to explore how height and time duration parameters affect g-forces on the rider. Students will drag control points on the Height vs. Time graph to adjust the acceleration. As the model runs, graphs of g-Force vs. Time and Vertical Velocity vs. Time are displayed. The apparent weight of the rider arises from the acceleration of gravity in combination with the acceleration of the elevator. If the elevator is stationary or moving with constant speed (i.e. not accelerating), riders feel their normal weight. If the elevator accelerates upwards, the rider feels heavier, whereas downward acceleration causes a sensation of lightness. With a strong enough downward acceleration, the rider can experience effective weightlessness or even negative g forces (requiring seat belts or restraints to avoid head trauma!).
The Free Fall Ride JavaScript Model was developed using the Easy Java/JavaScript Simulations (EJS) modeling tool. Although EJS is a Java program, EJS v5 and above can be used to create stand-alone JavaScript programs that run in almost any browser. Please note that this resource requires at least version 1.5 of Java (JRE). Editor's Note: The author has provided a user-friendly Student Guide that gives beginners instructions for setting initial inputs for a smooth, easy ride. Learners will have to figure out how to adjust the controls to produce a ride that is "thrilling, but not killing". The g-Force vs. Time graph is a great way to demonstrate that g forces can quickly exceed the level of human tolerance in a poorly designed ride.
