A.) skydiver The amount of air resistance is dependent upon two variables: For more information on physical descriptions of motion, visit The Physics Classroom Tutorial. Once the skydiver opens her parachute, force of air resistance and gravitational force becomes equal and hence the skydiver continues downwards with a constant velocity. Since the air resistance is acting in upward direction (opposing the downward motion of the skydiver) and the gravitational force is in the downward direction (accelerating the skydiver towards the earth), their sum becomes zero.
