Estimated Max Speed vs Slope Angle
How Snowboard Speed Is Estimated
Simplified Physics
Speed = sqrt(2 x g x Vertical Drop x Friction Factor)
Where g = 9.81 m/s^2 and the friction factor (0-1) accounts for snow friction and air drag.
Typical Speeds
Factors
Actual speed varies with wax quality, rider position (tucking vs standing), wind, temperature, and snow type.
Example Calculation
A 20° groomed slope, 500 m run length.
- 01Vertical drop = 500 x sin(20°) = 500 x 0.349 = 174.5 m.
- 02Speed = sqrt(2 x 9.81 x 174.5 x 0.7) = sqrt(2396) = 48.9 m/s.
- 03Speed in mph = 48.9 x 2.237 = 109.4 mph.
- 04Note: actual speed will be lower due to turning and speed-limiting technique.
