Interactive Experiment Guide
Start with fundamental scientific principles, launch the simulation, and verify mathematical predictions against real-time outcomes.
Scientific Foundation
Free fall describes motion governed by gravity. In an ideal vacuum, all bodies accelerate at a = -g independent of mass. When falling through a fluid medium, quadratic drag F_d = ½ρC_dA v² opposes motion until terminal velocity v_t = √(2mg / (ρC_dA)) is reached.
Interactive Simulation Flow
Launch the simulation workspace, adjust parameters in real time, and observe the immediate response in the telemetry and graphical indicator loops.
Frequently Asked Questions
Gravitational force is proportional to mass (F = mg), but acceleration is inversely proportional to mass (a = F/m = mg/m = g). Without air resistance, mass cancels out completely, giving every object identical acceleration.
