Crash Hazards

• Large decelerations can cause serious injury as the passenger experiences a large force.
• To reduce the force during collisions the time needs to increase as

  Force = Change in Momentum / Time
• To increase the time in collisions, seatbelts stretch slightly, airbags gradually slow you and crumple zones collapse inwards.
• Speed limits limit the momentum cars can travel at so reduce forces if a collision were to occur.
