How does air resistance in parachute cause decrease in acceleration which then reaches terminal velocity? Why? ... The force of air resistance, or drag, decreases as speed decreases. When the parachute is first opened, the force of drag is much greater than the force of gravity, so the rate of descent (vertical speed) decreases.
