Two burglars run down an alley at night, trying to escape the cops. Jack is carrying a rigid metal safe. Jill is carrying an armful of antique quilts. In the pitch dark, they both collide headlong into a concrete wall. 1. Who do you think will be hurt more in the collision, and why? Jack, the burglar carrying the rigid metal safe, will be more hurt in the collision. This is due to the harsh impact of the safe colliding with the concrete wall, as opposed to the impact faced when the quilt hits the wall. 2. During a car crash, what features of the car might act like either Jack’s safe or Jill’s quilts? In the case of a car crash, the impact of the metal crumple zone of the car (the front of it that gets harmed in a crash) will take the role of Jack’s safe, while Jill’s quilt will resemble the cushioning of an airbag, preventing severe injuries. Gizmo Warm-up When cars were first invented, the safety of passengers was not a great concern. As vehicles grew larger and faster, accidents became more deadly. Safety features went from being a rare luxury to a legal requirement. In the Crumple Zones Gizmo, you will design cars that will help a crash test dummy survive a collision. 1. To begin, do not make any changes to the DESIGN tab of the Gizmo. Select the CRASH TEST tab, and click Play ( ). After the crash, click Slo-mo replay. What happens? The car collided with the concrete wall without anything to prevent the harsh impact, resulting in a severe car crash.
