Terminal Velocity vs Mass
Fórmula
Terminal Velocity
Terminal velocity is reached when air drag equals gravitational force, producing zero net acceleration.
Derivation
Setting weight equal to drag: m*g = (1/2)*rho*v²*Cd*A
Solving: vt = sqrt(2*m*g / (rho*A*Cd))
Ejemplo Resuelto
A skydiver (80 kg, belly-down, A = 0.7 m², Cd = 1.0) in standard atmosphere.
- 01vt = sqrt(2 * m * g / (rho * A * Cd))
- 02vt = sqrt(2 * 80 * 9.81 / (1.225 * 0.7 * 1.0))
- 03vt = sqrt(1569.6 / 0.8575)
- 04vt = sqrt(1830.6)
- 05vt ≈ 42.8 m/s ≈ 154 km/h
Preguntas Frecuentes
What is a typical terminal velocity for a skydiver?
About 55 m/s (200 km/h) in a belly-down position, or up to 90 m/s (320 km/h) in a head-down dive.
Does mass affect terminal velocity?
Yes. Heavier objects (with the same shape) reach higher terminal velocities because more gravitational force is needed to balance drag.
What is the drag coefficient?
A dimensionless number that characterizes the aerodynamic drag of an object. A sphere has Cd around 0.47; a flat plate perpendicular to flow is about 1.28.
