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.

Basic addition sums! You can do these, right…. 1) 1 + 1= 2) 24 + 36= 3) -50 + 10= 4) -12 + 130 5) 35 + -5 6) 10,000 + -5,000 7) -120 + -120
