get_air_resistance
estimates air resitance in Newtons
get_air_resistance( velocity, bodymass = 75, bodyheight = 1.75, barometric_pressure = 760, air_temperature = 25, wind_velocity = 0 )
velocity | Instantaneous running velocity in meters per second (m/s) |
---|---|
bodymass | In kilograms (kg) |
bodyheight | In meters (m) |
barometric_pressure | In Torrs |
air_temperature | In Celzius (C) |
wind_velocity | In meters per second (m/s). Use negative number as head wind, and positive number as back wind |
