get_air_resistance: Get Air Resistance

Description

get_air_resistance estimates air resistance in Newtons

Usage

get_air_resistance(
  velocity,
  bodymass = 75,
  bodyheight = 1.75,
  barometric_pressure = 760,
  air_temperature = 25,
  wind_velocity = 0
)

Value

Air resistance in Newtons (N)

Arguments

velocity

Instantaneous running velocity in meters per second (m/s)

bodymass

In kilograms (kg). Default is 75kg

bodyheight

In meters (m). Default is 1.75m

barometric_pressure

In Torrs. Default is 760Torrs

air_temperature
