Shuttlecock Speed Calculator
Calculate the effective shuttlecock speed and travel time accounting for air density at altitude.
How to Use the Shuttlecock Speed Calculator
- Enter the initial smash speed in km/h.
- Enter the altitude of the venue in meters.
- Click Calculate to see effective speed and travel time over half the court (6.7m).
Casos de Uso
- •Analyzing smash effectiveness at high-altitude tournaments.
- •Understanding how venue conditions affect shuttle selection.
- •Sports science research on badminton biomechanics.
Fórmula
Formula: Air density factor = (1 - 0.0000226 × altitude)^5.256. Effective speed = initial speed × drag coefficient × √(air density factor). Travel time over 6.7m = distance / average speed.
Perguntas Frequentes
How fast is a professional badminton smash?
Professional smashes typically reach 300–400 km/h off the racquet, making badminton the fastest racquet sport. The shuttlecock decelerates rapidly due to high aerodynamic drag.
Does altitude affect shuttlecock speed?
Yes. At higher altitudes, thinner air reduces drag, causing the shuttlecock to fly faster and farther. Badminton federations use heavier shuttlecocks at high-altitude venues.
What is the effective speed vs smash speed?
Due to extreme drag, a shuttlecock loses about 30–40% of its speed by the time it crosses the net. The effective speed at the net is what matters for the opponent's reaction time.
