Listing 10 of 105 questions
shows a sky-diver falling vertically downwards at terminal velocity. Y X Arrows X and Y show the two main forces acting on the sky-diver. State the name of force X and the name of force Y. X Y Explain why force Y acts upwards. When the sky-diver first started to fall, forces X and Y were unbalanced. Describe and explain the effect of the unbalanced forces on the motion of the sky-diver. State what happened to the size of force X and the size of force Y as the sky-diver fell and reached terminal velocity.
