1. Baseline (flightpath E): Label and name the forces involved in a falling parachutist.
Further (flightpath D): Describe the affect the pairs of forces have on the velocity of the Parachutist.
Challenge (flightpath C,B&A): Resolve the resultant force of each pair of forces and represent it as a single force.
