🧪 Classroom Classroom Technology Simulation

A classroom digital photogate timer: drop objects of different mass and drag through two light gates, measure real fall time and air resistance, and compute experimental gravitational acceleration g.

This simulator models a classroom "smart lab" technology: a digital photogate timer used to measure free fall precisely. Adjust the mass and the drag-coefficient-times-area of a dropped object — steel ball, foam ball, or a flat card disc — release it, and watch it fall past two light gates whose crossing times are logged automatically. The app numerically integrates gravity against quadratic air drag every frame, computes the object's instantaneous speed and an experimental value of g from the two gate timestamps, and estimates the terminal velocity implied by the current mass and drag settings — showing directly how weight and air resistance change what a falling-object experiment actually measures.

Adjust the weight and friction of falling objects to investigate how different technologies impact classroom physics experiments and student learning outcomes.
