What is the significance of the distribution of force over a larger area in the context of airbags and seatbelts?

• It increases the damage to the vehicle

• It decreases the pressure on any single point of the body, reducing potential injury

• It makes the force more concentrated

• It has no significant effect on safety

Newton's Third Law of Motion states that for every action, there is an equal and opposite reaction. How does this law apply to the operation of airbags in a car crash?

• The airbag inflates and pushes against the passenger as much as the passenger pushes against it

• The airbag prevents any reaction from occurring

• The airbag decreases the mass of the passenger

• The airbag increases the action force, reducing the reaction force

In the context of car safety features, why is it important for forces during a collision to be absorbed or spread out over time?

• It increases the total energy of the system

• It reduces the impact force experienced by the passengers

• It makes the collision last longer

• It ensures the car travels further after impact

How do airbags help to protect passengers during a collision?

• By increasing the force of impact

• By decreasing the time over which the impact occurs, spreading out the force

• By making the car heavier

• By ejecting the passenger to avoid collision
