Body Crash

The video explains the importance of safety devices like airbags and seatbelts in cars. It discusses how these devices reduce the force experienced by passengers during a collision by extending the time over which deceleration occurs. Airbags deploy automatically to cushion the impact, while seatbelts stretch to ease the body to a halt. These mechanisms significantly reduce the risk of serious injury or fatality in car accidents, saving thousands of lives annually.

What happens to the objects inside a car when it comes to a sudden stop?

• They remain stationary.

• They continue moving at the car's previous speed.

• They move forward at a slower speed.

• They move backward.

Why are airbags crucial during a car collision?

• They prevent the car from moving.

• They alert emergency services.

• They provide a cushion for the driver's head.

• They slow down the deceleration of the driver's body.

How do airbags reduce the risk of injury?

• By stopping the car immediately.

• By inflating slowly over several seconds.

• By reducing the average force on the body.

• By preventing the car from rolling over.

What is the primary function of seatbelt fabric during a collision?

• To remain rigid and unyielding.

• To tighten and restrict movement.

• To stretch and absorb force.

• To break upon impact.

How do seatbelts and airbags together contribute to car safety?

• By gradually bringing the body to a stop.

• By making the car more aerodynamic.

• By providing entertainment during the drive.

• By ensuring the car does not start.
