- A falling body on Earth will generally not fall at constant acceleration in reality, due to air resistance (or drag). The equation for the drag force Fd isFd = 0.5 (Cd A) ρ v2where Cd is the unitless drag coefficient of a body (which depends on the body's density and other properties), A is its cross-sectional area as it falls, ρ is the density of the air, and v is the body's velocity with respect to the atmosphere.
