• Draw a causal loop diagram to describe the
  followingAs the sky diver falls she travels
  faster and faster until reaching a terminal
  velocity. Include divers speed, air resistance,
  net downward force, and downward acceleration in
  your diagram.

• Draw a causal loop diagram to describe the
  followingAs a car travels down the highway it
  maintains a speed near the goal of the speed
  limit. Include cars speed above speed limit,
  gas pedal depression, and acceleration in your
  diagram.
