Understanding Airbags and Momentum

What is the primary function of an airbag in a vehicle?

• To enhance the car's fuel efficiency

• To increase the speed of the car

• To provide comfort during long drives

• To protect passengers by reducing the impact force during a crash

What happens to a passenger's momentum when a car comes to a sudden stop?

• It increases

• It drops to zero instantly

• It remains constant

• It decreases gradually

According to Newton's second law, what is the relationship between force and momentum change?

• Force is equal to the square of momentum change

• Force is unrelated to momentum change

• Force is directly proportional to the rate of momentum change

• Force is inversely proportional to momentum change

How do airbags help in reducing the impact force during a collision?

• By allowing the momentum to change more quickly

• By extending the time over which momentum changes

• By increasing the speed of the car

• By making the car heavier

What additional benefit do airbags provide besides reducing impact force?

• They make the car more aerodynamic

• They enhance the car's braking system

• They spread the impact force over a larger area

• They increase the car's mileage
