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
