Terminal Velocity Formula
Formula
vₜ = √(2mg / (ρACₐ))
Where:
- • vₜ = terminal velocity (m/s)
- • m = mass (kg)
- • g = gravitational acceleration (m/s²)
- • ρ = fluid density (kg/m³)
- • A = cross-sectional area (m²)
- • Cₐ = drag coefficient
Common Terminal Velocities
- • Skydiver: ~55 m/s (120 mph)
- • Raindrop: ~9 m/s (20 mph)
- • Baseball: ~43 m/s (95 mph)
- • Parachutist: ~5 m/s (11 mph)
