Free Fall with Air Resistance

Simulate falling motion with quadratic drag using Euler integration and inspect position/velocity trends over time with configurable units.

Use Cases

  • - Estimate descent time with realistic drag effects
  • - Compare trajectory sensitivity to Cd and frontal area
  • - Preview terminal approach behavior in early design checks
  • - Validate classroom examples numerically

Model

  • Drag force: Fd = 1/2 * rho * Cd * A * v^2
  • Acceleration: a = g - Fd / m
  • Integration: explicit Euler time stepping
